Answer:

The ladder is approximately 12.65 feet high on the building.

Step-by-step explanation:

Since the ladder forms a right triangle with the building, we can apply Pythagora's theorem to calculate the last side, this is done below:

$14^2 = 6^2 + h^2\\h^2 = 14^2 - 6^2\\h^2 = 196 - 36\\h^2 = 160\\h = \sqrt{160}\\h = 12.65$

The ladder is approximately 12.65 feet high on the building.

In triangle ABC, if AC is congruent to CB, angle A = 3x + 18, angle B = 7x - 58, & angle C = 2x - 8, find x & the measur

sukhopar [10]

Answer:

Angle A = 75°

Angle B = 75°

Angle C = 30°

Explanation:

If AC is congruent to CB, from figure given we have angle A = angle B.

Angle A = 3x + 18

Angle B = 7x - 58

Angle C = 2x - 8

We have,

3x + 18 = 7x - 58

4x = 76

x = 19

So,

Angle A = 3*19 + 18 = 75°

Angle B = 7*19 - 58 = 75°

Angle C = 2*19 - 8 = 30°
