What is the answer? i also dont get what it asking for

y = 180 - 2x

y = 2x

Explanation:

The first sentence says "Two angles of a triangle are congruent", so let's say x represents each of those congruent angles. The third angle (let's call it y) has twice the measure of each of those x angles. This means y = 2x.

Since y = 2x, the answer must be choice C.

Notice that the three angles x, x and y add to 180 as they are part of a triangle

x+x+y = 180

2x+y = 180

y = 180-2x

Extra info: because y = 2x and y = 180-2x, we can set the two right hand sides equal to each other. We get the equation 2x = 180-2x and it solves to x = 45. This means y = 90. This is an isosceles right triangle.

y=x+2 hope this jdjxhdnzbdjdo
