Question

The angle of a triangle are in the ratio 5:7::8find angle in grades.​

Answer 1

Answer:

45°, 63°, 72°

Step-by-step explanation:

Ratio= 5:7:8

So, the values are 5x, 7x, 8x.

The sum of interior angles of triangle equals to 180 °

(5x + 7x + 8x) = 180

20x = 180

x = 9

The angles are,

5x = 5×9 = 45°

7x = 7×9 = 63°

8x = 8×9 = 72 °

Answer 2

Step-by-step explanation:

measure of angles in degree

1. 45 degree
2. 63 degree
3. 72 degree

1 grade is equal to 100 minutes

1 grade is equal to 1.67 degree

1 degree is equal to 1/1.67 degree

now measure of angles in grade is equal to

1. 45 degree equal to 26.946=26.95
2. 63 degree equal to 37.724=37.72
3. 72 degree equal to 43.113=43.11
