The measure of angle RQS is 50°.

Solution:

Given data:

m(ar QTS) = 260°

<u>Tangent-chord theorem:</u>

<em>If a tangent and chord intersect at a point, then the measure of each angle formed is half of the measure of its intercepted arc.</em>

$ m \angle PQS  = \frac{1}{2}\times m(ar \ QTS)

              $  = \frac{1}{2}\times260^\circ

              =130^\circ

m∠PQS = 130°

<em>Sum of the adjacent angles in a straight line is 180°.</em>

m∠PQS + m∠RQS = 180°

130° + m∠RQS = 180°

Subtract 130° from both sides.

130° + m∠RQS - 130° = 180° - 130°

m∠RQS = 50°

The measure of angle RQS is 50°.

What is the simplified form of ? 12x6 12x18 72x6 72x18
andreev551 [17]

Answer:

12*x^18

Step-by-step explanation:

144=(2^4)*(3^2)

then

sqrt (144 x^36)=sqrt (144)*sqrt (x^36) 

sqrt (144)=sqrt ((2^4)*(3^2))=2² * 3=12

sqrt (x^36) =x^(36/2)=x^18

therefore

sqrt (144 x^36)=sqrt (144)*sqrt (x^36)=12*x^18

the answer is 12*x^18

5x+1=20 what do x equal
frez [133]
X = 3.8

5x+1=20
Subtract 1 on both sides to get:
5x=19
Divide by 5 on both sides to get:
x=19/5

You can leave it as a fraction as 19/5, or convert to a decimal as 3.8.
