Find m∠CXY
Please help with this, this is for my test review!!!

137°

Step-by-step explanation:

All angles in a triangle add up to 180° always.

Now imagine the two smaller shapes as a bigger triangle, CED.  The measure of angle CED is 89°, and CDE is 48°.  Do the math, and angle DCE is 43°.

But notice how the corresponding sides of the two smaller shapes are congruent.  (CX=XE, and DY=YE)  Meaning, the measure of angle C is equal to the measure of angle YXE.

We're almost there.  CXY (what we're looking for) and YXE are supplementary angles, meaning the angle measures add up to 180.  180-43 = 137°.

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.
