Answer:
Angle A = 68 degree
Angle B = 44 degree
Step-by-step explanation:
Sum of all interior angles = Angle A+Angle B+ Angle C
180 = 68+x+x-24
180 = 68+2x-24
180-68 = 2x-24
112+24 = 2x
136/2 = x
68 = x
Therfore, Angle A = 68 degree
Angle B = (x-24)
= (68-24)
= 44 degree

If you estimate
7 times 7=49 so the square root of 46 is less than 7
6 times 6= 36 so the square root of 46 is more than 6
so if you do it on a calculator the answer is 6.78
