Question

Please solve question number 8 & 9 and explain it​

Answer 1

8. in isoscles triangle opposite angles are equal so let the other two angle be x°

so, 55°+2 x° = 180° [ angle sum property of a triangle ] 2x° =180°-55°

x°=125/2 =62.5°

Answer 2

Answer:

8. 55° and 70°, 9. 90° and 42°

Step-by-step explanation:

8. One of the two equal angle is 55°

Hence another equal angle will also be 55°

Let unknown angle be x°

then x+55+55= 180°

=→ x= 180-55-55°

=→ x= 70°

9. A right angle triangle has one 90°

one of the acute angle is 48°

let unknown angle be x

then x+90+48= 180°

=→ x= 180-90-48°

=→ x= 42°

Hope my answer helps you.
