Answer:

If it is asking for the angle then it is 68 degrees

Step-by-step explanation:

Since lines AR and AC are the same that means angle A and C are the same, in which you make the equation 3x+23=5x+1 and solve that resulting in x = 11. From there you plug in 11 to get angle A and C equaling 56, so 56+56=112. Then from there you subtract 180-112 to get 68 degrees.

Yes.

The given triangle ️ ARC is an isosceles triangle (it's given that the sides AR = RC). If 2 opposite sides are equal then the 2 opposite angles will also be equal.

So,

A = C

=》3x + 23 = 5x + 1

Using this,

3x + 23 = 5x + 1

3x - 5x = 1 - 23

-2x = -22

x = -22/-2

x = 11

Measure of A = 3x + 23

= 3(11) + 23

= 33 + 23

= 56°

Measure of C = Measure of A = 56°

Now,

R = ?

R = 180 - (A + R) [Angle Sum Property]

R = 180 - (56 + 56)

R = 180 - 112

R = 68°
