Question

Two angles measure (70 + 2x)° and (3x – 15)°. If each angle is the supplement of the other, then the value of x is Choose the correct option: a) 25 b) 30 c) 20 d) 35

Answer 1

Answer:

answer is 25 ( 70+2x)° + (3x-15)°

Answer 2

Answer:

The value of x is 25°

Explanation:

Two angles are said to be supplementary angles because they combine to generate a linear angle when their sum is 180 degrees.

(70 + 2x)° + (3x – 15)° = 180°

5x+55°=180°

5x=180°-55°

5x=125°

x=25°

Addition:

The act of combining two or more items is known as addition. The process of computing the sum of two or more numbers in mathematics is called addition. It is a fundamental mathematical procedure that is frequently used in daily life. One-digit numbers can be added simply for solving addition problems, however for bigger numbers, we divide the numbers into columns using their corresponding place values, such as ones, tens, hundreds, thousands, and so on.
