Andrew constructed a triangle so that the measurement of <1 and <2 were congruent. If angle 3 measured 70 degrees, what is the measure of angel 1?

A) 35
B) 55
C) 70
D) 110

Answer 1

The answer will be B 55
because 55+55+70=180

Answer 2

Answer:

Its 55

Step-by-step explanation:

The total angles of a triangle is 180 degrees. subtract 70 from that and you get 110. Then because both 1 and 2 are congruent you divide 110 equally by 2 and get 55.

Don't know if this made sense but hope it helped :)
