Answer:

x = 8.6 cm

Step-by-step explanation:

To find x, we need to take the sin ratio of the 35° angle.

Identity

sin∠x = opposing side length / length of hypotenuse

Solving

sin35° = 0.57
sin35° = x/15
⇒ x/15 = 0.57
⇒ x = 15 × 0.57
⇒ x = 8.55 cm
⇒ x = 8.6 cm

Measure of Angle 1 is 5x. Measure of Angle 3 is x-24. What is the measure of Angle 1?

olga55 [171]

Answer:

The answer to your question is: 30°

Step-by-step explanation:

Data

m∠ 1 = 5x

m∠ 3 = x - 24

Process

m ∠ 1 = m ∠ 3 because they are vertical angles

5x = x - 24

5x - x = 24

4x = 24

x = 24 / 4

x = 6

Angle 1 = 5(6)

= 30°
