Answer:
base angles each measure 68 degrees
third angle measures 34 degrees
Step-by-step explanation:
let '2x' = measure of each base angle
let 'x' = measure of third angle
the sum of all three must equal 180 degrees so you can write this equation:
2x + 2x + x = 180
combine 'like terms' to get:
5x = 180
divide each side by 5 to get:
x = 34
therefore, twice 'x' is 68
check:
68 + 68 + 34 = 180
180 = 180
