    |dw:1353828858730:dw| Since AB=AC triangle ABC is an isosceles triangle. So y=5x-40 y and 5x are supplementary angles y+5x=180 5x-40+5x=180 10x-40=180 Can u find x @Kagome_gurl8?

    being an isosceles triangle, <SRT = <STR = 5x-40 Now, <STR + <STU = 180 degrees - they both form a linear angle. => 5x-40 + 5x = 180 , Solve it for x now :)

    well the base angles of an isosceles triangle are equal, so since that angle in the bottom left of the triangle is 5x - 40, then so is the angle on the bottom right... and the angle on the bottom right and the angle just outside the triangle are what we call a linear pair, and a linear pair are two angles that add up to 180 degrees, and just as shown above, you add those two angles together to get 180 and solve for x.
