Answer:
65 degrees.
Step-by-step explanation:
It's hard to explain, but I'll try:
The outside of the first two angles is 105 and 140. Half a whole angle is 180. So, you do
180-140=40. The inside is 40.
And then 180-105=75.
Then you add the two and subtract them from 180:
40+75= 115
180-115=65
Voila!
A tangent forms a right angle with the centre of circle at the point it touches the circumference. i.e. OAB = 90 degrees
If AOB = 55 degrees, then ABO = 90 - 55 = 35 degrees
The answer is C) collateral
Answer:
21 3/4 - 13 1/8 = 8 5/8 ft longer
Step-by-step explanation:
We subtract the blue rope from the green rope
21 3/4 - 13 1/8
We need to get a common denominator of 8
21 3/4*2/2 - 13 1/8
21 6/8 - 13 1/8
8 5/8
