Answer:
22.8
Step-by-step explanation:
A, and B are distractions. multippe C (11.4) by 2, you'll get 2C (22.8)
B because tangent is Opposite/hypotenuse. = 6/8 = 0.75
C equals 17.5 you have to cross multiply to find what c is equal to
5). Radius = 6 km. Circumference = 12π km. Area = 36π km²
6). Diameter = 8 mm. Circumference = 8π mm. Area = 16π mm²
10(x/2 + 8) = 11, expand
10x/2 + 80 = 11
5x/2 = 11-80= -69
5x = -138
x = - 138/5
