Iknow it equals 180 i’m just confused.

A whole triangle is total of 180°

as the two angles are same which is x, hence it is an isosceles triangle.

so using all the angles given,

46° + x° + x° = 180

by collecting all the like terms,

46° + 2x° = 180

GET RID of 46° on the left hand side
ADD of 46° on the right hand side

2x° = 180° - 46°
2x = 134°

now divide all with 2

2x÷2 = 134÷2
x° = 67°

therefore, the answer is x = 67°

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
