Question

Write an equation you could use to find the length of the missing side of the right triangle. Then find the missing length. Round to the

nearest tenth if necessary.
18 cm
15 cm
с cm
Oa. 18° +15° = c?: 549 cm
O b. 18 + 15 = c; 32 cm
c. 152 + 2 = 18: 9.9 cm
Od. 18+15° = 2:23.4 cm

Answer 1

d. 18^2 + 15^2 = c^2. 23.4

Explanation:

Right triangle: c^2 = a^2 + b^2

with c is the hypotenuse, a and b are the other sides

c^2 = 18^2 + 15^2

c^2 = 324 + 225

c^2 = 549

c = 23.4
