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

Answers

Answer:

x = 24.7

Step-by-step explanation:

Here, we want to find the value of x

To do this, we are to use the appropriate trigonometric ratio

From what we have;

9 faces the angle given as it is the opposite, x is below and it is the adjacent

The trigonometric identity that links opposite to adjacent is the tan which is the ratio of former to latter

Thus, we have that;

tan 20 = 9/x

x = 9/tan 20

x = 24.7

Pls answer and I will mark brainliest!

Answers

Answer:

C. 244°

Step-by-step explanation:

Angle formed by two tangents is equal to half of the difference of intercepted arcs:

m∠C = 1/2(arcAXB - arcAB)64° = 1/2(mAXB - mAB)mAXB - mAB = 128°

The sum of the same two arcs is a full circle:

mAXB + mAB = 360°

Add the two equations together:

2mAXB = 360° + 128°2mAXB = 488°mAXB = 244°

Correct choice is C

Admission to the fair is $15 each ride cost $3 micah spent a total of $36 he spent all of his money on rides and admission

Answers

Answer:

7

Step-by-step explanation:

Admission cost = $15

Cost per ride = $3

Total amount spent = $36

We can obtain the number of rides thus :

Let number of rides = x

Admission cost + (cost per ride * number of rides) = total amount spent

15 + 3x = 36

3x = 36 - 15

3x = 21

x = 21 / 3

x = 7

Number of rides = 7

Coral snakes are brightly colored, highly venomous snakes with red, yellow, and black bands along their bodies. Another species of snake, called the scarlet king snake, has similar bands of red, black, and yellow. Which of the following describes the conditions that resulted in a large population of king snakes with these types of markings? King snakes and coral snakes relied on similar food sources that contributed to their unique coloring.Since king snakes with these markings were avoided by predators, they were able to survive to pass on this trait to offspring.Coral snakes mated with king snakes often enough to produce another species of king snake with the red, black, and yellow.Overproduction of offspring increased the likelihood that the genetic mutation leading to these bands would spontaneously occur.
