Answer:
D & E
Step-by-step explanation:
Angle A would be 10 degrees.
Complementary angles add to 90 degrees.
So 90-80=10
Just put the numbers under one square root symbol and try to simplify.
Answer:
<u>∠J = 31.06°</u>
Step-by-step explanation:
Taking the inverse sin function :
- sin ∠J = 1.6/3.1
- J = sin⁻¹ (0.516)
- <u>∠J = 31.06°</u>
Answer:
x = 90°
y = 43°
Step-by-step explanation:
We know that one angle equals 47°.
The two triangles are right triangles, so that makes x = 90°.
To find y, we add 90 + 47.
That would give us 137°.
All triangles add up to 180°.
180 - 137 = 43.
43° is the answer.
