An isosceles triangle has base angles that each measure 69o. Which equation can be used to find x, the measure of the third angl
e?
a
138 + x = 180
b
69 + x = 180
c
138 + 2x = 180
d
2x + 69 = 180
1 answer:
Answer:
a. 138 + x = 180
Step-by-step explanation:
Because the angles given are 69+69
which equal 138
and x being the missing angle
finally the total of all angles in a triangle = 180
