Answer:
Given information: WY=ZX, A is the midpoint of WY and A is the midpoint of ZX.
To prove : WA =ZA
Proof:
A is the midpoint of WY, it means A divides WY in two equal parts.
So, WY is twice of WA.
.... (1)
A is the midpoint of ZX, it means A divides ZX in two equal parts.
So, ZX is twice of ZA.
... (2)
(Given)
Substitute the values from equation (1) and (2).
Divide both sides by 2.
Hence proved.
Okay so you would use cos? = adjacent/hypotenuse so cos? = 31/57 so to find the angle you would do cos^-1(31/57) = ? so ? = 57.05 degrees. make sure your calculator is in degree mode
Answer:
o.42
Step-by-step explanation:
Answer:
y + 4 = -3(x + 1)
Step-by-step explanation:
point-slope form : y - y2 = m (x - x2)
In this case m = -3 and x2 = -1, y2 = -4
So
The equation in point-slope form
y + 4 = -3(x + 1)
A graph shows x-3 to be a factor, selection B.
The factorization would be (7x +3)(x -3).
