Find the value of x, rounded to the nearest degree explain how to find this. i know that it's sine/cosine ratios but i'm not sure hwo to set it up.

x =

Step-by-step explanation:

Use Sine rule:

As per the statement:

From the given figure:

Opposite side = 7 units

Hypotenuse side = 15 units

Using sine rule:

⇒

Simplify:

x = 27.8181392847 degree

Therefore, the value of x rounded to the nearest degree is,

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
