Help? which one should I choose

x = 80, y = 40

Step-by-step explanation:

Both triangles are isosceles, 2 congruent sides, so the base angles are congruent.

Triangle on left

base angles are congruent and equal to 50° , then

x = 180° - (50 + 50)° ← sum of angles in triangle = 180°

x = 180° - 100° = 80°

Triangle on right

base angles are congruent and equal to y , then

y = = = 40°

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
