Answer:
tanA = sinA / cosA = 3/5 / 4/5 = 3/4.
Answer:
I think this is the answer
Step-by-step explanation:
angle 3

angle 4

angle 2 is 49
angle 1

Answer:
<4 = 22
Step-by-step explanation:
<4 = x
x + 158 = 180
x = 22
The answer is 64, happy to help!

Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
