Equilateral triangles have three equal angles, so we right away know that x=60º. Then, we just solve (3(60)-70)º, which is 110º, for the answer.
Answer:
110°
Step-by-step explanation:
tringale have 180° right so firstly 180°-60°=120°
then 120°÷2 = 60° so x =60 okay you got it so just sum the 3x-70° and youll get it
im sorry i have bad eng
hope the answer is right
