Answer:
Step-by-step explanation:
<u>I'm assuming the angles are in degrees.</u>
<span>f(x) = 2x + 3
</span><span>g(x) = x²-7
</span>(f+g)(x) = f(x) + g(x) = 2x + 3 + x² - 7 = x² + 2x - 4
(f+g)(x) = x² + 2x - 4

Find RST
To do this, we use:
--- angle on a straight line
Make RST the subject
<em>Hence, the measure of RST is 144</em>
