Question

Find the area of the triangle with A = 60°, b = 11 feet, and c = 8 feet. Round to the nearest tenth.

Answer 1

41.25 ft^2

Explanation:

Literally all you need to do is Pythagorean Theroem.

a = ?

b = 11ft

c = 8ft

a^2 + b^2 = c^2

a^2 + 11^2 = 8^2

a^2 + 121 = 64

64 - 121 = a^2

a = 7.5

Then area of a triangle formula is (bh)/2

(11 x 7.5)/2 = 41.25
