400
Find the m<CBA.
m<CBA = 68 degrees.
500
If the m<2 is 37 degrees, what is the m<7 AND what is the angle relationship?
m<7 = 37 degrees AND they are Alternate Exterior Angles
500
If the m<5=98°, then the m<3 AND m<4 are:
m<3 = 82 degrees.
m<4 = 98 degrees.
500
If the m<4 = 5x+3 and the m<6 = 8x-5, then find the m<4.
First, x = 14.
So m<4 = 73 degrees.
