Step-by-step explanation:
Step-by-step explanation:
the triangle is an isosceles triangle hence the base angles are equal
sum of angles in a triangle is 180°, therefore, the top angle =180-(62+62)
the top angle =56°
h°= the top angle because alternate angles are equal
hence, h=56°
Answer:
(f/g)(4) = 3
(f + g)(4) = 28
Step-by-step explanation:
(f/g) = ![\frac{x^2+2x-3}{x^2-9}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2%2B2x-3%7D%7Bx%5E2-9%7D)
(f + g) = ![2x^2 + 2x -12](https://tex.z-dn.net/?f=2x%5E2%20%2B%202x%20-12)
Simply plug in 4 for x in both equations to find you answer!
Answer:
-2
Step-by-step explanation:
because the slope is 2, a perpendicular line must be the inverse
the equation for y1 is y=2x+1
y2= -2y+1
Answer:
Your expression equals
assuming the problem was to simplify
to the form
.
Step-by-step explanation:
![2\sin(\frac{\pi}{8}) 2\cos(\frac{\pi}{8})](https://tex.z-dn.net/?f=2%5Csin%28%5Cfrac%7B%5Cpi%7D%7B8%7D%29%202%5Ccos%28%5Cfrac%7B%5Cpi%7D%7B8%7D%29)
![2(2)\sin(\frac{\pi}{8})\cos(\frac{\pi}{8})](https://tex.z-dn.net/?f=2%282%29%5Csin%28%5Cfrac%7B%5Cpi%7D%7B8%7D%29%5Ccos%28%5Cfrac%7B%5Cpi%7D%7B8%7D%29)
Let's use the following identity: ![2\sin(A)\cos(A)=\sin(2A)](https://tex.z-dn.net/?f=2%5Csin%28A%29%5Ccos%28A%29%3D%5Csin%282A%29)
![2\sin(2 \cdot \frac{\pi}{8})](https://tex.z-dn.net/?f=2%5Csin%282%20%5Ccdot%20%5Cfrac%7B%5Cpi%7D%7B8%7D%29)
which is comparable to the form
.
![a=2](https://tex.z-dn.net/?f=a%3D2)
![\theta=\frac{\pi}{4}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cfrac%7B%5Cpi%7D%7B4%7D)
