Question

Solve for A 1.
A 1 = ?°
(I've tried answering 0, it isnt right.)​

Answer 1

angle1= 55

Explanation:

180-125=55

(complementary angles

or

angles in a triangle are 180 so

180-(88+37)

180-125

55

Answer 2

Answer is 55 degrees. Literally ‘angles on a straight line’, which is 180 degrees total so if we minus 180 by 125 the we get 55 degrees. You can even cross check the answer by adding all 3 angles: 37+88+55(the angle which you just found) it will altogether add to 180 degrees.
