5. Help Me Ill Give You Brainliest If U Get This Right

Answers

Answer 1

Answer: D.) 2

Step-by-step explanation:

In a rhombus, all sides are congruent; they have the same lengths (like a square). This means that if this parallelogram was a rhombus, 14 - x and 2x + 8 will have to be equal.

14 - x = 2x + 8

Subtract 2x from both sides

14 - 3x = 8

Subtract 14 from both sides

-3x = -6

Divide both sides by -3

x = 2

A triangular pane of glass has a height of 42 inches and an area of 546 square inches. What is the length of the base of the pane?

Answers

Answer:

Base = 26 in

Step-by-step explanation:

Recall the formula for the area of a triangle as:

Area = (Base x Height) / 2

In our case, this formula converts into:

546 in^2 = Base x 42 in /2

multiply both sides by 2 to get rid of fractions:

1092 in^2 = Base x 42 in

divide both sides by "42 in" to isolate the Base completely

1092 in^2 / 42 in = Base

Therefore Base = 26 in
