Answer:
Step-by-step explanation:
→ Write out the direct proportion equation
y = kx
→ Substitute in x = 21 and y = 8
8 = 21k
→ Divide both sides by 8 to isolate k
k = 2.625
→ Substitute back into original equation
y = 2.625k
→ Substitute 9.5 for k
y = 2.625 × 9.5 ⇔ 24.9375
Answer:
77 degrees
Step-by-step explanation:
Right triangles always add up to 180 degrees. We know that one angle is 23 degrees, angle A is missing, and the last angle is a right angle which is equal to 90 degrees. Knowing what we know, we must subtract the two known angles from 180 to get angle A.
180 - 90 = 90
90 - 23 = 77
Angle A is equal to 77 degrees.
hope this helps!! :]
