Question

two angles are supplementary and the larger is 40 degree less than the three times the smaller. find the smaller angle​

Answer 1

Step-by-step explanation:

Given:

The larger angle is 40 degree less than the three times the smaller.

To find:

The measurement of the smaller angle .

Solution

Let the smaller angle be x.

Let the larger angle be 3x-40

What is supplementary angle ?

Angle which is equal to 180°.

$= > x + (3x - 40) = 180$

$= > x + 3x - 40 = 180$

$= > 4x = 180 - 40$

$= > 4x = 140$

$= > x = \frac{140}{4}$

$= > x = 35$

: Smaller angle's measure is 35°.
