Question

special name of this triangle.
8. One of the angle of a triangle is 80° and the other angles are equal, find the each equal angle.
9. If the ratio of angles of a triangle is 2:3:4, find the measure of each angle.
6 ZR, find the measure of ZP, 20 and ZR.​

Answer 1

Step-by-step explanation:

8. Let the two same angles in triangle be x

Now, As we know the sum of internal angles of a triangle is 180. so,

80 + x +x = 180

2x = 180 - 80

2x = 100

x = 100/2

x = 50°

Hence both other angles are

50°

each.

9.Let the angles are 2x, 3x and 4x. According to the angle sum property, the sum of interior angles of a triangle is 180 degree. The value of x is 20. Therefore the angles of triangle are 40, 60 and 80.
