Answer:
D 133 degrees
Step-by-step explanation:
The measure of an angle external to a circle = the difference of the two arcs intercepted divided by 2
47 = [ (360 - x) - x ] / 2
94 = 360 - 2x
x = 133 degrees of the arc
Answer:
x=4/3
Step-by-step explanation:
cross multiple and solve from there
6x+8=16
6x+8-8=16-8
6x=8
×=8/6
simplify
x=4/3
Answer:
216 ft^2
Step-by-step explanation:
area of a triangle: (height * base)/2
in this problem,
height = 12, base = 36
area = 12*36/2 = 6*36 = 216
216 ft^2
Answer:
168 in
Step-by-step explanation:
Pythagoras says:
b² + 56² = 70²
so
b² = 70² - 56²
b = √1764 = 42
so the perimeter is 70+56+42 = 168
£11000 is the tax free allowance, so we deduct 11000 from 45600=34600. This qualifies for the 40% rate. That comes to £13,840.
