Answer:
The angle is 52 degree.
Step-by-step explanation:
length of of side, L = 8
Hypotenuse, H = 13
According to the trigonometry,
![cos y = \frac{L}{H}\\\\cos y = \frac{8}{13}\\\\cos y = 0.62\\\\y = 52^0](https://tex.z-dn.net/?f=cos%20y%20%3D%20%5Cfrac%7BL%7D%7BH%7D%5C%5C%5C%5Ccos%20y%20%3D%20%5Cfrac%7B8%7D%7B13%7D%5C%5C%5C%5Ccos%20y%20%3D%200.62%5C%5C%5C%5Cy%20%3D%2052%5E0)

Answer:
A=10x^2+14x
Step-by-step explanation:
A=wL
w=2x
L=5x+7
A=2x(5x+7)
A=10x^2+14x
Answer:
1 equilateral triangle
Step-by-step explanation:
Given
Shape: Equilateral Triangle
Side length = 8cm
Required
Determine the number of triangles
From the question, we understand that the triangle is equilateral and the length of a side is 8cm.
This implies that the length of other sides will also be 8cm.
So, only one triangle can be constructed and their side lengths is 8cm.
