The perimeter of a yield sign in the shape of an isosceles triangle is 22 feet if the shortest side is 2 feet less than the other two sides find the length of the shortest side

If this is saying that the shortest side is two less than the other side (which is equivalent to the last side)
x-2+x+x=22
3x-2=22
3x = 24
x = 8, the shortest side would then be 2 less, or 6 feet

OR if this is saying the shortest side is 2 less than the sum of the other two sides:
2x-2+x+x = 22
4x-2 = 22
4x = 24
x = 6, OR the shortest side is 4 feet.

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

step-by-step explanation:

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

              cross multiply

            divide both sides by 32
