Question

An isosceles triangle has one angle with a measure of 30°. What could the measure of the other two angles be?

30° and 30°
30° and 120°
75° and 75°
30° and 100°
*I think it is 75 to 75*

Answer 1

IT is more then one

Answer 3

questions ?

Answer 4

I dont get how to find the x

Answer 5

hope you know that an isoscel triangle has two sides and the corresponding two angles congruent

yes ?

Answer 6

Yea i know that

Answer 7

and hope you know that the sum of angle measures of a triangle is equal 180 degrees

yes ?

Answer 8

yea

Answer 9

I know everything about then i think

Answer 10

ok

given that one angle measure of this triangle from your posted problem has 30 degrees

so 180-30=150 what mean that the sum of other two angles of the presently triangle is 150 degrees

but we know that this 150 degrees is the sum of two congruent triangles so

x +x = 150

how you get the x value ?

Answer 11

@supie

Answer 12

x +x = 2x

2x = 150 divide both sides by 2 and get

2x/2 = 150/2

x = 75

do you understand it now ?

Answer 13

Yea

Answer 14

ok
