In TriangleARC, m AngleA = 70°. What is the measure of arc AC?
rusak2 [61]
I found the image that should have accompanied this problem.

The triangle inside the circle is an isosceles triangle. It has 2 equal sides and 2 equal angles. 

Angle A = 70° , Angle C is also 70°. This leaves angle R having 40°.

The arc opposite angle R is twice the measure of its angle.

Angle R = 40°
Arc AC = 40° x 2 = 80°

The measure of arc AC is 80°.

Vita wants to center a towel bar on her door that is 27 1/2 inches wide. She determines that the distance from each end of the t
timurjin [86]

Answer:

The equation is x+18 =\frac{55}{2}..

The length of the towel bar is \frac{19}{2}\ in \ \ \ OR \ \ \ 9\frac{1}{2}\ in..

Step-by-step explanation:

Given,

Length of the door = 27\frac{1}{2}\ in

we can rewrite 27\frac{1}{2}\ in as  \frac{55}{2}\ in.

We have to find out the length of the towel bar.

Let the length of towel bar be 'x'

`Since Vita wants that the distance from each end of the towel bar to the end of the door to be 9 inches.

So we can say that the length of the towel bar plus  from each end of the towel bar to the end of the door plus  from each end of the towel bar to the end of the door  is equal to length of door.

framing in equation form, we get;

x+9+9= \frac{55}{2}\\\\x+18 =\frac{55}{2}

Hence The equation is x+18 =\frac{55}{2}.

Now we solve the equation we get;

Subtracting both side by 18 we get;

x+18-18=\frac{55}{2}-18\\\\x=\frac{55}{2}-18

Now we will make the denominator common we get;

x=\frac{55}{2} -\frac{18\times2}2= \frac{55}{2} -\frac{36}2 = \frac{55-36}{2}=\frac{19}{2}\ in \ \ \ OR \ \ \ 9\frac{1}{2}\ in

Hence The length of the towel bar is \frac{19}{2}\ in \ \ \ OR \ \ \ 9\frac{1}{2}\ in.
