Answer:

The original angle measures $90^{\circ}$ .

Step-by-step explanation:

We are asked to find the measure of original angle, when a ray divides an it into two complementary angles.

We know that two complementary angles add up-to 90 degree.

Therefore, the original angle is a right angle or the measure of original angle is $90^{\circ}$ .

The ball is shaped like a hemisphere with a radius of 5 inches. Find the volume of the bowl

PilotLPTM [1.2K]

Answer:

The volume of the bowl is $V=\frac{250}{3}\pi\ in^{3}$ or $V=83\frac{1}{3}\pi\ in^{3}$

Step-by-step explanation:

we know that

The volume of a hemisphere (bowl) is equal to

$V=\frac{4}{6}\pi r^{3}$

we have

$r=5\ in$

substitute

$V=\frac{4}{6}\pi (5)^{3}$

$V=\frac{250}{3}\pi\ in^{3}$

$V=83\frac{1}{3}\pi\ in^{3}$

It’s the slope formula i’m pretty sure . So it would be 5-5 and then 3-2 . so 0/-1

Look at the figure. How can you prove the triangles are congruent?

<h3>Answer: SSS Postulate</h3>

The tickmarks tell us which pairs of sides are the same length.

AB = BC due to the single tickmarks
AD = CD due to the double tickmarks

So far we have two pairs of congruent sides.

The third pair of congruent sides are the overlapping or shared sides BD = BD which is true by the reflexive property (anything is congruent to itself).

Overall we have three pairs of congruent sides allowing us to use SSS. Each "S" stands for "Side".

C = 4x + 5y, the value of "x" when C = 51 & y = -3 is:<br> =16.5<br> =9<br> =-16.5<br> =13

Oksi-84 [34.3K]

Answer:

16.5

Step-by-step explanation:

Just put in the values of C and y first into the expression.

C = 4x + 5y

Put in values.

51 = 4x + 5(-3)

Evaluate.

51 = 4x + (-15)

Swap positions.

4x + (-15) = 51

Shift (-15) to the other side and change to (+15).

4x = 51 + 15

= 66

Find x.

x = 66 ÷ 4

x = 16.5
