Major arc is the remaining arc of the circle, so that
major arc+minor arc = 360 degrees.
For this particular problem,
Major arc = 360 - minor arc = 360-97=263 °
So to set up the equation we have:
<span><span><span>4M</span><span>4+M</span></span>=<span>127</span></span>
<span>28M=12(4+M)</span>
<span>28M=48+12M</span>
<span>28K−12M=48</span>
<span>(28−12)M=48</span>
<span>16K=48</span>
<span>M=<span>4816</span></span>
<span>M=3</span>

Step-by-step explanation:
you can figure this out by taking 105 and keep subtracting 15 until you reach 0 then see how many times you needed to use 15
Step-by-step explanation:
The triangles are congruent due to Hypotenuse-Leg congruence. (HL congruence)
Each of the triangles have a right-angle, a congruent hypotenuse and a congruent side of the triangle.
Therefore Triangles ABC and PRQ are congruent.
