Answer:

A = 58

B =:25

Step-by-step explanation:

C = A + B

83 = 9x + 4 + 4x + 1

83 = 13x + 5

13x = 78

x = 78/13

x = 6

A = 9x + 4 = 9 x 6 + 4 = 58

B = 4x + 1 = 4 x 6 + 1 = 25

What is the missing angle in the right triangle?
Ainat [17]

Answer:

68

Step-by-step explanation:

For angle A, 3 is the adjacent leg. 8 is the hypotenuse.

The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.

\cos A = \dfrac{adj}{hyp}

\cos A = \dfrac{3}{8}

\cos A = 0.375

We know the cosine of angle A equals 0.375. We take the inverse cosine of 0.375 to find the measure of the angle.

A = \cos^{-1} 0.375

A = 68^\circ
