The sum of the angles of a triangle ALWAYS sum up to 180 degrees. So to find the other angle, you would take 180, subtract 90, and then subtract 26, to get 64.
The measure of the 3rd angle equals 64.

Answer:

∠QSR = 78°
∠SQR = 51°

Step-by-step explanation:

The measure of an inscribed angle (QTR) is half the measure of the arc it intercepts. The measure of an arc is the same as the measure of the central angle it intercepts. So, we have ...

∠QSR = 2×∠QTR

∠QSR = 2×39°

∠QSR = 78°

Sides SQ and SR are radii of circle S, so are the same length. That means triangle QRS is an isosceles triangle and the base angles SQR and SRQ are congruent. The sum of angles in a triangle is 180°, so we have ...

∠QSR + 2(∠SQR) = 180°

78° + 2(∠SQR) = 180° . . . . fill in the value we know

2(∠SQR) = 102° . . . . . . . . . subtract 78°

∠SQR = 51° . . . . . . . . . . . . .divide by 2
