Answer:
Angle 2 & 4 = 72
Step-by-step explanation:
Angle 7 is corresponding to angles 3.
So, since we know angle 7 = 108, then angle 3 = 108.
Angle 3 is supplementary to angle 2, which means they add up to 180º.
So if angle 3 = 108.
Then:
Angle 2 + 108 = 180
Angle 2 = 72º.
Angle 2 & angle 4 are vertical angles, so they have the same measure. Therefore,. If angle 2 is 72º, then angle 4 has to also be 72º.
Hope this helps! Have a great day!
The answer is forty inches
Answer:
sin 25
Step-by-step explanation:
sin(A − B) = sinA cosB − cosA sinB
sin 155
sin( 180 -25)
A = 180 B = 25
sin180 cos25 − cos180 sin25
Sin 180 = 0
cos 180 = -1
0 - (-1) sin 25
sin 25
