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 68.7 cm2 161.7 cm2 381.3 cm2 450.0 cm2

Answer 1

Answer:

Option B is the correct answer.

Step-by-step explanation:

We have one side = 27.6 cm

Hypotenuse = 30 cm

Length of remaining side $=\sqrt{30^2-27.6^2}=11.76cm$

Area of right angled triangle $=\frac{1}{2}\times \texttt{Product of lengths of 2 sides other than hypotenuse}$

Area $=\frac{1}{2}\times 27.6\times 11.76=161.7cm^2$

Option B is the correct answer.
