MDE = 128 and mBC = 63. Find mZA. (The figure is not drawn to scale.)​

We know that the measure of a whole circle = 360°

So the measure of central angle;

360 - (128 + 63)

360 - 191

169

Measure of angle A would be half the measure of the central angle so;

169/2

m∠A = 84.5°

Hope this helps!

its c or d   take a lucky guess my dude

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
