The answer is 22.8
Cos 64 = adj./hypotenuse
Cos64=10/x
X(cos64)=10
X= 10/cos64
= 22.8
Answer:
Step-by-step explanation:
I did the math and what i got was x=116
1)y=3x
2)y=x
3)y=7x
4)y=x+7
4)y=2x+1
6)y=12x+2
Answer:
A = 28x^2
Step-by-step explanation:
The area of a triangle is equal to
A = 1/2 b*h
The base is 7x and the height is 8x
A = 1/2 (7x)*(8x)
A = 1/2 (56x^2)
A = 28x^2
