An isosceles triangle is one in which 2 angles have similar
measure while the other one is different. In this case, the 2 vertex angles
have a measure of 42 degrees, therefore the third angle which is equal to (2x +
3) is:
(2x + 3) + 42 + 42 = 180
2x + 3 = 96
<span>x = 46.5°</span>
Answer:
A symmetric property
Step-by-step explanation:
20% of x=6
20/100 of x=6
20x= 600
x=30
38% of 30=11.4
