Answer:
It is a right triangle
Step-by-step explanation:
Ok, so the √113 ≈ 10.6
So we we know that that is the biggest side.
The pythagorean theorem : a² + b² = c², where a and b are the legs ( the two smaller sides) and c is the hypotenuse (the longest side of the triangle)
We can input what we know, as 7 and 8 are the smallest sides and √113 is the longest
7² + 8² = (√113)²
49 + 64 = 113
113 = 113
This is a right triangle.

Answer:
m<AIR = 90 deg
Step-by-step explanation:
I assume the problem contains an error, and that AR is a diameter, not AC.
Look at the diameter of the circle, AR. It passes through the center of the circle, C. You can think of the two radii of the circle, CR and CA, as sides of angle RCA. Since AR is a diameter, and AR is a segment which is part of line AR, rays CR and CA are sides of an angle that lie on a line. That makes the measure of angle RCA 180 deg. Angle RCA is a central angle of circle C since its vertex is the center of the circle.
Angle AIR is an inscribed angle in circle C since its vertex is on the circle itself. If an inscribed angle and a central angle intercept the circle at the same two points, then the measure of the inscribed angle is half the measure of the central angle.
m<AIR = (1/2)m<RCA = (1/2) * 180 = 90
m<AIR = 90 deg
