Answer:

Correct Answer: Option A

Step-by-step explanation:

cos(x + 25o) = sin 45o

using cos θ = sin(90 - θ)

cos(x + 25o) = cos(90 - 45)

cos(x + 25o) = cos 45

x + 25 = 45

x = 45 - 25

x = 20o

 

Hope it helps ♡^▽^♡

Answer:

a) x = 6°  b) m∠B = 50°

Explanation:

(a) total angle measure of a triangle is 180°

8x + 2 + 70° + 60° = 180°

8x + 132° = 180°

8x = 180° - 132°

8x = 48°

x = 6°

(b)

m∠B = 8x + 2

m∠B = 8(6) + 2°

m∠B = 48° + 2°

m∠B = 50°
