Step-by-step explanation:
We have AB = 7, Angle ABC = 70°
and Angle ACB = 90°.
Angle BAC = 180° - 70° - 90° = 20°
(Sum of angles in a triangle = 180°)
Using Trignometry,
AC = 7sin70° = 6.58.
BC = 7cos70° = 2.39.
28 degrees is the answer , 76+76= 152, 180-152+ 28
58.50
10%= 4.50
5%= 2.25
6.75*2= 13.50
45+ 13.50= 58.50
43000 is your answer I know because I know
