180 degrees is the answer
x^2 - 81 = 0. Add 81 to each side.
x^2 = 81. Take the square root of each side.
x = 9, -9
2/22 to simplify 1/11 not sure though but I think that’s the answer u can double check though
Answer:
Are also equal
Step-by-step explanation:
Say triangle A has the angles 30 and 60. triangle b also has those angles. Total angle of any triangle is 180 so 180-60-30 = 90 for triangle A and it is also the same for triangle b. Thus 90 = 90 angles are the same.
