Answer:

200

Step-by-step explanation:

Substitute 15 for y

\frac{1}{5} x - 10 = 30

\frac{1}{5} x = 40

x = 200

Hi there!

The formula for the area of a triangle is A = 1/2(b x h). Using the information provided, all we have to do is plug in what we know and solve!

WORK:
74 = 1/2(b x 9.14)
148 = b x 9.14
b = 16.2 inches (approximately)

Hope this helps!! :)
