I’m pretty sure it is 98 degrees because you are supposed to double the angle of the arc...if that makes sense. Please correct me if I am wrong! Sorry if this doesn’t help much.

Answer:

122°

Step-by-step explanation:

The sum of interior angles in a triangle is 180°

<B + 70° + 49° = 180°

<B = 61°

The arc that sees angle B is twice of it so

The measure of arc BC is 2 × 61 = 122°

Answer:

$\large\boxed{m\angle R\approx76^o}$

Step-by-step explanation:

$\dfrac{\sin R}{SQ}=\dfrac{\sin S}{RQ}\\\\\text{We have:}\\\\SQ=32,\ RQ=26,\ S=52^o\to\sin52^o\approx0.788\\\\\text{Substitute:}\\\\\dfrac{\sin R}{32}=\dfrac{0.788}{26}\qquad\text{multiply both sides by 32}\\\\\sin R\approx0.97\to R=\arcsin(0.97)\\\\R\approx76^o$
