Answer:
m∠8 = 49°
Step-by-step explanation:
∠7 and ∠8 are same-side interior angles.
Remember, same-side interior angles are supplementary. This means that the sum of the angles is 180°.
Let's use the variable 'x' to represent the unknown measure of angle ∠8.
![131 +x=180](https://tex.z-dn.net/?f=131%20%2Bx%3D180)
(cancels itself out)
![180-131=49](https://tex.z-dn.net/?f=180-131%3D49)
![x=49](https://tex.z-dn.net/?f=x%3D49)
Therefore, the measure of ∠8 is 49°.
Answer:
p < -32
Step-by-step explanation:
<em>Given:</em> p/-8 + 9 > 13
<em>Rewrite:</em>
+ 9 > 13
<em>Subtract 9 from both sides:</em>
> 4
<em>Move the negative (it is a fraction): </em>
> 4
<em>Multiply both sides by 8:</em> -p > 32
<em>Times by -1 (-p -> -1p): </em>p > -32
<em>Flip the sign (multiplied by a negative): </em>p < -32
Hope this helps, have a nice day :D
