Answer:
The measure of the top-left angle in the triangle is <u>4</u><u>8</u><u> </u><u>°</u> and the measure of the bottom-right angle is <u>4</u><u>2</u><u> </u>°.
Step-by-step explanation:
We know that , the sum of angles of triangle is 180 °.
And , It is the right triangle so, bottom left is 90 °.
8 x ° + 7 x ° + 90 ° = 180 °
15 x + 90 ° = 180 ° ..( combine like terms)
Subtract each side by 90°
15 x° + 90° - 90° = 180° - 90°
15 x° = 90 °
15 x° / 15 = 90 ° / 15 ..(Divide each side by 15°)
x° = 6 °.
Using value of x to finding the
- The measure of the top left angle in the triangle is = 8 x° = 8 × 6 = <u>4</u><u>8</u><u> ° </u>.
- The measures of the bottom right angle is = 7 x ° = 7 × 6 = <u>4</u><u>2</u><u> </u><u>°</u> .
