Answer:

x= 20

Step-by-step explanation:

1. multiply both sides by 20: 16x-5x= 220

Answers:

x = 6 and P = 128

=================================================================

Explanation:

The tangents CT and CU are equal to each other. The rule is that tangent segments that meet at a common point are the same length.

Let's solve for x

CT = CU

3x = 18

x = 18/3

x = 6

Because CT = 18, this makes BC = BT+TC = 12+18 = 30

---------------------------

For similar reasoning as mentioned earlier, we can say tangents BT and BV are the same length. This means BV = 12.

Segment CD = 52 and CU = 18, which makes UD = CD-CU = 52-18 = 34

From there, we can say segment DV = 34 also. This leads to BD = BV+VD = 12+34 = 46

Triangle BCD has the three sides

  • BC = 30
  • CD = 52
  • BD = 46

The perimeter is

P = sum of the three sides

P = (side1)+(side2)+(side3)

P = BC + CD + BD

P = 30+52+46

P = 82+46

P = 128

Which point lies on the bisector of angle PQR ?
Natalka [10]

The point that lies on the bisector of angle PQR in the diagram given is: point Y.

<h3>What is an Angle Bisector?</h3>

An angle bisector is a segment that cuts an angle into two equal parts.

From the image given, point Y lies directly opposite to vertex Q. Point Y divides angle PQR into equal parts.

Therefore, the bisector of angle PQR is: point Y.

A) Find the value of 8^1/3<br>B) Find the value of 8^2/3<br>C) Find the value of 16^3/4​
lorasvet [3.4K]

Step-by-step explanation:

A.

{8}^{ \frac{1}{3} }  =  \sqrt[3]{8}  = 2

B.

{8}^{ \frac{2}{3} }  =  {  (\sqrt[3]{8}) }^{2}  =  {2}^{2}  = 4

C.

{16}^{ \frac{3}{4} }  =  { (\sqrt[4]{16} )}^{3}  =  {2}^{3}  = 8
