Answer:
Angle B is 41 degrees
Step-by-step explanation:
1) find the supplement of the 113 degree angle; it is 180-113, or 67, degrees.
2) recognizing that the sum of the interior angles of a triangle is 180 degrees, add up 67 and 72 degrees, obtaining 139 degrees, and subtract this sum from 180 degrees:
180 degrees - 139 degrees = 41 degrees (answer)
The steps are outlined above; the end result is that <B is 41 degrees.
Answer:20474.7
Step-by-step explanation:
68249 divide by 10 then multiply by 3
You can immediately see that the vertex is located at (-3,-2) and that the y-intercept is 7 or very close to 7.
The general equation for a parabola with vertex at (h,k) is
y-k = (x-h)^2, and from that and the given info, we get:
y-(-2) = (x-(-3))^2, or y+2 = (x+3)^2, or y = (x+3)^2 - 2.
