If m<1 = 29° and m<2 = 92°, what is m<3?

A. 63°
B. 59°
C. 121°
D. 122°

Answer 18

all of your questions are similar
add your 2 given angle measures so it is set up like
29+92+x=180
now solve for x which is the missing measure
121+x=180
x=59
59 degrees

Answer 19

remember the 3 angles of a triangle always add up to 180
