Answer:
x=30° y=5
Step-by-step explanation:
All sides of the top triangle are equal. And all angles are equal Since it's an equilateral triangle.
so
8y=40
y=40/8
y=5
Since it's an equilateral triangle. All angles are equal And each angle has dimensions
=180°/3=60°
The angle of the straight line = 180°
so The obtuse angle of the lower isosceles triangle is 180°-60°=120°
The angles at the base of the isosceles triangle are equal
so 2x° = 180°-120°
2x°=60°
x°=60°/2
x°=30°
Dang...I literally had this question in Algebra the other day, and got it wrong....but i believe the actual answer was B. It was for sure not D XD. Sorry if I am wrong yet again.
The answer is f(x) = 0.25(5.25)x
I belive your answer is 3
