Find the value of x for each triangle

A) 45° 90° 45°

B) they are complementary

C) the triangles will have two equal angles and one larger angle

Step-by-step explanation:

Hello from MrBillDoesMath!

The measure of x is 45 degrees in all triangles.  

As each triangle has two equal legs (shown by the tick marks) the base angles opposite those legs are equal. But a triangle has 180 degrees  2x + 90 = 180, or 2x = 180-90 =90, so x = 45. All three triangles are 45-90-45 triangles.

Thank you,

MrB

answer: i can’t tell you that

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
