Answer:
x ≈ 61.8
Step-by-step explanation:
Using the sine ratio in the right triangle
sin15° =
=
( multiply both sides by x )
x × sin15° = 16 ( divide both sides by sin15° )
x =
≈ 61.8 ( to the nearest tenth )
Answer:
compute its exterior angle as 360/18, which is 20 degrees
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
2x - 7 = -x - 1
(add x on both sides)
3x - 7 = -1
(add 7 on both sides)
3x = 6
(divide both sides by 3)
x = 2
