Answer:

f(-3) = -4

Step-by-step explanation:

f(x) = -2x² - 3x + 5

f(-3) = -2(-3)² - 3(-3) + 5

f(-3) = -2(9) + 9 + 5

f(-3) = -18 + 9 + 5

f(-3) = -9 + 5

f(-3) = -4

We can solve this problem in different ways:

0. Statement: As angle 1 and 3 are vertical angles, and angle 1, 5, 4 form a straigth angle, so angle 2 and (algle 4 + angle 5) are vertcal angles too.

Reason:

$\begin{gathered} \angle1+\angle4+\angle5=180=\angle2+\angle3(share\text{ the same line)} \\ \angle1=\angle3(verticl\text{ angles)} \\ So, \\ \angle4+\angle5=\angle2 \end{gathered}$
