Answer:

10

Step-by-step explanation:

{14}^{2}  = ( {9}^{2}  +  {x}^{2} )

196 = 81 +  {x}^{2}

196 - 81 =  {x}^{2}

115 =  {x}^{2}

x =  \sqrt{115}

X = 10.7

Given: Two concentric circles with AB tangent to smaller circle at R<br> Prove: AR=RB
disa [49]

Answer:

See explanation

Step-by-step explanation:

If segment AB is tangent to the smaller circle, than AB⊥OR. Consider two right triangles AOR and BOR. In these triangles:

  • OR is common leg;
  • AO=OB as radii of larger circle;
  • ∠ARO=∠BRO, because AB⊥OR.

By HL theorem, ttriangles AOR and BOR are congruent. This gives you that AR=RB.

If two angles are congruent, then they are vertical angles? True or False. If true explain your reasoning. If false, give an cou
Bond [772]
This statement is false as all vertical angles are considered congruent but not all congruent angles are considered vertical angles. Any obtuse or acute angle may be considered congruent. If the angle from point A to B is 110 and the angle between B to C is 110 as well then they are congruent

Which formula shows a joint variation?
djyliett [7]

The answer is the first option: I, II and III.

The explanation is shown below:

1. By definition, there is a joint variation  when a variable depends on two or more different variables. Therefore, you can express it as following:

y=kxz

Where x,y and z are the variables and k is the constant of proportionality.

As you can see, y is directly proportional to x and z.

2. Keeping the information above, you have:

I) V=lwh (V varies jointly with l, w and h.

II) V=\frac{1}{3}r^{2}h\pi (If \frac{\pi}{3} is the constant of proportionality, V varies jointly with r^{2} and h).

III) V=Bh (V varies jointly with B and h.
