8(4) - 2 = 30
15(4) = 60
All triangles equal 180 degrees and there is already a right angle. 60 plus 0 is 90, and 90 plus 90 (or 90 times 2) is 180
60 + 30 = 90
90 + 90 = 180

Answer:
yes
Step-by-step explanation:
If GH║FE, then ∆DEF ~ ∆DHG.
In similar triangles, corresponding sides have the same ratios.
The ratios of corresponding sides are ...
DG/DF = DH/DE
DG/(DG + GF) = 18/(18+36)
(1/2GF)/((1/2GF +GF) = 1/3
(1/2)/(3/2) = 1/3
1/3 = 1/3
Corresponding sides are proportional. Angle D is congruent to itself, so ∆DEF ~ ∆DHG by the SAS similarity postulate. Angles DGH and DFE are therefore congruent and GH║FE.
Lauren went shopping for a new pair of pants because of a sale. The price on the tag
was $20, but Lauren paid $13 before tax. Find the percent discount.
Answers
Answer:
discount rate= 0.35
Step-by-step explanation:
Giving the following information:
The price on the tag was $20, but Lauren paid $13 before tax.
To calculate the discount rate, we need to use the following formula:
Total discount= total price * ( 1 - discount rate)
13= 20 * (1 - discount rate)
13= 20 - 20discount rate
20discount rate = 7
discount rate= 7 / 20
discount rate= 0.35
Solve the equation 17=5k-3
Answers
Answer:
4
Step-by-step explanation:
Simplifying
17 = 5k + -3
Reorder the terms:
17 = -3 + 5k
Solving
17 = -3 + 5k
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '-5k' to each side of the equation.
17 + -5k = -3 + 5k + -5k
Combine like terms: 5k + -5k = 0
17 + -5k = -3 + 0
17 + -5k = -3
Add '-17' to each side of the equation.
17 + -17 + -5k = -3 + -17
Combine like terms: 17 + -17 = 0
0 + -5k = -3 + -17
-5k = -3 + -17
Combine like terms: -3 + -17 = -20
-5k = -20
Divide each side by '-5'.
k = 4
Simplifying
k = 4

m<E = [tex]77^{o}[/tex]
Step-by-step explanation:
From the diagram, ΔACE and ΔBDE are similar. So that comparing its angles, we have;
(8x + 4) = (9x - 5)
8x + 4 = 9x - 5
5 + 4 = 9x - 8x
x = 9
Thus,
(8x + 4) = 8(9) + 4 = 76
(9x - 5) = 9(9) - 5 = 76
3x = 3(9) = 27
From ΔACE,
3x + (8x + 4) + m<E = 180 (sum of angles in a triangle)
27 + 76 + m<E = 180
m<E = 180 - 103
m<E = [tex]77^{o}[/tex]

Coefficient definition
Answers
Answer:
In mathematics, a coefficient is a factor linked to a monomium. Given a monomium divider, the coefficient is the ratio of the monomium by the divider. Thus the monomium is the product of the coefficient and the divider. The different coefficients will depend on the factorization of the monomium. This is usually next to the letter that accompanies the algebraic fraction. A numeric coefficient is a constant factor of a specific object. For example, in the expression 9x2, the coefficient of x2 is 9. In elemental algebra, numeric coefficients of similar terms are grouped together to simplify algebraic expressions.

In the following diagram overline DE || overline FG and overline KL perp FG. What is the measure of angle x?
Angle x = _____°
Answers
Given:
DE||FG and KL is perpendicular to FG.
To find:
The measure of angle x.
Solution:
If two lies intersect each other, then vertical opposite angles are equal.
[tex]m\angle ACB=63^\circ [/tex] (Vertically opposite angles)
[tex]m\angle BAC=x^\circ [/tex] (Vertically opposite angles)
KL is perpendicular to FG.
[tex]m\angle ABC=90^\circ[/tex]
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
In triangle ABC,
[tex]m\angle ABC+m\angle BAC+m\angle ACB=180^\circ[/tex]
[tex]90^\circ+x^\circ+63^\circ=180^\circ[/tex]
[tex]x^\circ+153^\circ=180^\circ[/tex]
[tex]x^\circ=180^\circ-153^\circ[/tex]
[tex]x^\circ=27^\circ[/tex]
Therefore, the measure of angle x is 27 degrees.

if it takes 3 men 5 hours to dig 12 holes, how many hours does it take for 3 men to dig 84 holes?
Answers
Answer:
Hence it will take 35hours
Step-by-step explanation:
Let the time it took to dig hole be x
Ley the number of holes be n
Using the relationship x = kn (direct relationship)
if it takes 3 men 5 hours to dig 12 holes, hence;
when x = 5, n = 12
k = x/n
k = 5/12
To get how many hours it take for 3 men to dig 84 holes, then;
when n = 84, x = ?
x = 5/12 * 84
x = 5 * 7
x = 35hours
Hence it will take 35hours
