Answer:
30°, 30° and 120°
Step-by-step explanation:
Using the information given in the question.
let x be the measure of each congruent base angle , then
the third angle = 3x + 30
Sum the 3 angles and equate to 180
3x + 30 + x + x = 180, that is
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
Thus
The 2 congruent bas angles are each = 30°
The third angle = 3x + 30 = 3(30) + 30 = 90 + 30 = 120°

Answer:</h2>
Since both angles are vertical angles, we need to set them equal to each other.
The final answer is <em>x = 10</em>.
The perimeter would be 7+7+4+4 or 14+8 which equals 22 and the area would be 7x4 which is 28
