Answer:
Cos x°=adjacent/hypotenuse
Cos x°=45/52
x°=Cos-¹(45/52)
x°=30°
Answer:
56°
Step-by-step explanation:
Because the two lines are parallel, the corresponding angles are equal. The two corresponding ∠s are ∠A and ∠B. ∠A=∠B
∠A=4x
∠B=2(x+14)
4x = 2 (x+14)
the right side requires the distributive property
a) 4x = 2x+28
2x = 28
x = 14
b) now plug in x for both ∠s to find ∠A and ∠B
∠A = 4x = 4(14) = 56°
∠B = 2(x+14) = 2(14+14) = 2(28) = 56°
I just did both angles to show that they are equal and it is a way to check your work
