Answer:
80.5°
Step-by-step explanation:
Every triangle is measured to be 180°. Subtract X which is 19 from 180
180-19=161
Because V and W are congruent, they are the same length. So you divide 161 by w to get 80.5
Answer:
-1
Step-by-step explanation:
2.5 - 3.5x = 8 - 4x - 6
0.5x = 2 - 2.5
0.5x = -0.5
x = -1

Determine g(x), if f(x) is reflected across the y axis
<em>When a function (x,y) is reflected across the y axis, the new function becomes (−x,y).</em>
<em />
In other words,

Calculating f(-x)


Substitute g(x) for f(-x)
