Find the measure of c. A. 40 B. 70 C. 90 D. 50
Juliette [100K]

Answer:

D. 50

Step-by-step explanation:

a = 90° (angle subtended in semicircle)

a + c + 40° = 180° (by angle sum postulate of a triangle)

90° + c + 40° = 180°

c + 130° = 180°

c = 180° - 130°

c = 50°

3(2x+14)divided by w-y if w=8,x=5,y=1 how do i solve this
Viktor [21]
\frac{3 (2x + 14)}{w - y}
w = 8, x = 5, y = 1

You have to first substitute every variable into its spot in the equation.

<span>\frac{3 (2x + 14)}{w-y}
</span><span>\frac{3 (2*5 + 14)}{8 - 1}
</span>
Then solve.

\frac{3 (28)}{7} = \frac{84}{7} = 12
