Answer:
x=7
Step-by-step explanation:
This is a right triangle, we can use sin , cos, and tan
tan theta = opposite side/ adjacent
tan 45 = 7/x
Multiply each side by x
x tan 45 = 7/x *x
x tan 45 =7
Divide each side by 45
x tan 45 / tan 45 = 7/ tan 45
x = 7 / tan 45
x =7
Answer:
it should be 5
Step-by-step explanation:
The circumference of a circle is C = 2<span>πr
Given C = 36</span><span>π, we can solve for the radius r:
r = C/2</span>π = 36π/2<span>π = 36/2 = 18 cm (ANSWER)
</span>
65+56=121, 180-121=59, 59/8=7.375 , so the answer is A
