Can someone help me with this? I’ve completely forgotten how to do it.

49

Step-by-step explanation:

A triangles angle must equal 180 when added together and since we have 2 given angles we can add them together.

45 + 86 = 131

Next we need to subtract 180 by 131 in order to find  angle 2

180 - 131 = 49

Therefor angle 2 is 49

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
