Answer:
∠ B = 19°
Step-by-step explanation:
note ∠ C = 90° ( angle in a semi- circle )
The sum of the 3 angles in the triangle = 180°, thus
∠ B = 180° - (90 + 71)° = 180° - 161° = 19°
Answer:
166.32
Step-by-step explanation:
14%+23%=37% 100-37=63
100%=264
63%=x
63x264=16632/100=166.32
-4(9-3)/(8-2) = -4
(8^2-2^5)/(24/6)+3^2= 17
5(16-5)-1/(4^2-7) = 6
