Answer 1

$\rm\bf\underline{Question:}$

The measure of angle of triangle are in the ratio 3:7:8. Find their

measure in degree and radian

$\rm\bf\underline{Answer:}$

Let the angles be 3x, 7x and 8x, then

3x+7x+8x= 180 [Sum of angles in a triangle=180]

=18x= 180

=x= 180÷18

=x= 10

Therefore the angles of the triangle are: 3x= 3×10= 30

7x=7×10=70

8x=8×10=80

Therefore the angles of the triangle are 30, 70 & 80.

Answer 2

Answer:

Let the angles be 3x, 7x and 8x, then

3x+7x+8x= 180 [Sum of angles in a triangle=180]

=18x= 180

=x= 180÷18

=x= 10

Therefore the angles of the triangle are: 3x= 3×10= 30

7x=7×10=70

8x=8×10=80

Therefore the angles of the triangle are 30, 70 & 80.
