Please Help!! Find the measure of angle X and angle Z

75

Step-by-step explanation:

By the Base Angle Theorem, if two sides of a triangle are equivalent (it is an isosceles triangle), then the two angles opposite to those sides are equal as well.

A triangle adds up to 180 degrees.

180-30

=150

150/2

=75

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
