Chapter 4: Q5. (page 165)

Complete each sentence with the most appropriate word, phase or value.
If $∠ 1$ and $∠ 2$ are complements and $m ∠ 1 = 74$ , then $m ∠ 2 =$ ________.

Short Answer

Expert verified

The answer is 16 .

Step by step solution

- Define complementary angles.

Two angles are said to be complementary if their sum is equal to $90^{\circ}$ .

- State the explanation.

The sum of complementary angles is $90^{\circ}$ .

Then,

$\begin{matrix} ∠ 1 + ∠ 2 = 90 \\ 74 + ∠ 2 = 90 \\ ∠ 2 = 90 - 74 \\ ∠ 2 = 16^{\circ} \end{matrix}$

Hence, the blank is filled by $16^{\circ}$ .

- State the conclusion.

Therefore,“If $∠ 1$ and $∠ 1$ are complements and $m ∠ 1 = 74$ , then $m ∠ 2 =$ 16”.
