Question

A right triangle has one angle that measure 23o. The adjacent leg measures 27.6 cm and the hypotenuse measures 30 cm.What is the approximate area of the triangle? Round to the nearest tenth.Area of a triangle = bh

Answer 1

Area of a triangle is given by half the product of two of the sides and the sine of the included angle.

Thus, the area of the triangle is 0.5 x 27.6 x 30 x sin 23^o = 161.76 cm^2
