The last number line the correct answer!
-2a-5>3
-2a>8
a<-4

( the sign is flipped in the end because when you multiply or divide by a negative number, the sign flips the other way around)

Angles U and V are supplementary angles. The ratio of their measures is 7:13 Find the measure of each angle

GREYUIT [131]

If $u$ and $v$ are <span>supplementary angles, then

$u+v=180^{\circ}~~~~~\mathbf{(i)}$

The ratio of $u$ and $v$ is $\dfrac{7}{13}:$ <span>

$\dfrac{u}{v}=\dfrac{7}{13}\\\\\\ u=\dfrac{7v}{13}~~~~\mathbf{(ii)}$

Substitute $\mathbf{(ii)}$ into $\mathbf{(i)}:$

$\dfrac{7v}{13}+v=180^{\circ}\\\\\\ \left(\dfrac{7}{13}+1 \right )\cdot v=180^{\circ}\\\\\\ \left(\dfrac{7}{13}+\dfrac{13}{13} \right )\cdot v=180^{\circ}\\\\\\ \dfrac{20}{13}\cdot v=180^{\circ}\\\\\\ v=180^{\circ}\cdot \dfrac{13}{20}\\\\\\ \boxed{\begin{array}{c} v=117^{\circ} \end{array}}$

From $\mathbf{(i)},$ we find the measure of $u:$

$u=180^{\circ}-v\\\\ u=180^{\circ}-117^{\circ}\\\\ \boxed{\begin{array}{c} u=63^{\circ} \end{array}}$

Planes A and B intersect in line s. If point Vis a point on line s, then it lies on:

Trava [24]

Answer:

Option C.

Step-by-step explanation:

It is given that planes A and B intersect in line s.

It means, all points lie on the line s must be lie on both plane A and B because s is the line of intersection of both plane A and B.

It is given that V is a point on line s.

Since, the point V lies on line s, therefore it is also lies on both plane A and B.

Hence, the correct option is C.
