Given:

The figure of a rhombus QRST.

To find:

A. The value of x.

B. The measure of angle RQP.

Solution:

A. We need to find the value of x.

We know that the diagonals of a rhombus are perpendicular bisectors. It means the angles on the intersection of diagonals are right angles.

m\angle RPS=90^\circ                       [Right angle]

(5x+15)^\circ=90^\circ

(5x+15)=90

5x=90-15

5x=75

Divide both sides by 5.

x=\dfrac{75}{5}

x=15

Therefore, the value of x is 15.

B. We need to find the measure of angle RQP.

From the given figure, it is clear that

m\angle RQP=(2x+3)^\circ

Putting x=15, we get

m\angle RQP=(2(15)+3)^\circ

m\angle RQP=(30+3)^\circ

m\angle RQP=33^\circ

Therefore, the measure of angle RQP is 33 degrees.

2x + 1.5x +20 = 90 
3.5 x = 90-20 
3.5 x = 70 
x = 70/3.5 
x = 20 
angle DAE = 2*20 = 40 
angle CAD = 1.5*20 +20 = 50

Answer:

  1. FALSE
  2. TRUE
  3. TRUE

Step-by-step explanation:

<u>1.</u>

  • Non-standard units can be used to measure volume
  • Examples : m³, in³, cm³, mm³, L

<u>2.</u>

  • The volume of a rectangular prism can be found by multiplying the length, width, and height
  • <u>V = lwh</u>

<u />

<u>3.</u>

  • If there are smaller units, then naturally more of the units will be used
  • If there are larger units, then less of the units will be used

Rachel has a box in the shape of a prism with a square base. The capacity of the box is 150 cubic inches. The height of the box
Alex777 [14]

Answer:

Step-by-step explanation:

What do we know about that prism?

It's a rectangular prism with a square base.

Height: y (from question)

base length: x (from question)

base width: x (from question, since it's a square base).

Total volume: 150 cu inches

The question lacks a relationship between x and y the "is __ times", but we can see from the answer choices that they all show a constant relationship:

y = 1.5 x  

The volume of a prism is obtained by  multiplying the lengths of its 3 dimensions: V = length * width * height.  In our case, we then have

150 = x * x *  y

then we replace y by its x-expressed equivalent:

150 = x * x * (1.5x) = 1.5x³

then we isolate x³ by dividing each side by 1.5

x³ = 100, we do the cubic root on each side

x = 4.64

So, answer is D. x = 4.6 and y = 6.9

If you you 4.64 * 4.64 * 6.96 = you get 149.8, which is very close to 150.
