So what is the question just comment on this I can help
Answer:
116 degrees
Step-by-step explanation:
angle d looks obtuse, but not so obtuse, and the only obtuse option is 116 deg
To find the answer,we can set an equation adding up all the angles:
a°+2a°+2a°+a°=360°
6a°=360°
a°= 360°/6
a = 60
Therefore,the answer is 60.
Hope it helps!
Hello!

Recall that the transformations form of a parabola is:
f(x) = ±a(b(x-h)) + k where:
a = vertical stretch/compression
b = horizontal stretch/compression
h = horizontal shift, x-coordinate of vertex
k = vertical shift, y-coordinate of vertex
In this instance, the parent function is f(x) = 3x^2. There is a vertical stretch of 3.
However, there is a point (7, -2) that needs to be included. Substitute these values into the transformation formula:
h = 7
k = -2
f(x) = 3(x - 7)² - 2 is the equation with (7, -2) as the vertex.
