Question

If one of the angles of an isosceles triangle is 100°, the measure of other two equal

angles is

a) 70° and 70° b) 40° and 40° c) 50° and 50° d) 38° and 38°​

Answer 1

Answer:

every triangle has the total angle as 180 degrees

in you have to do 180-100

it is 100 degrees

as it is an isosceles triangle then that means it has 2 equal sides so it has to be 40 and 40

hope this helps if it does then pls thank me and mark as brainliest thank you . :)

Answer 2

sum of triangle is 180°

measure of one angle is 100°

let one of the equal angle is X

then

X+X+100= 180

2x+100= 180°

2x= 180-100

X= 80/2

X= 40

measure of equal angles are 40 and 40(b)
