Answer:
79°
Step-by-step explanation:
Line pu is a straight line meaning it has a measure of 180°.
37+34+30=101
180-101=79
Answer:
AC = 18
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° = 
, then
cos30° = 
= 
= 
= ( cross- multiply )
2 AC = 12
× = 12 × 3 = 36 ( divide both sides by 2 )
AC = 18
Answer:
x = 38°
y = 90°
Step-by-step explanation:
x = 180° - 90° - 52° = 38°
y = 90° because it has a right angle.
Answer:
you're correct...
