In triangle QRS the measurement of an angle RSQ is 29.1 and the measure of angle QRS is 80 degrees what is the measurement of sqr

The measurement of ∠SQR is 70.9 degrees

Step-by-step explanation:

To find the total angle of any polygon, use the formula = 180 (n-2)

The "n" is number of sides a polygon have. Triangle has 3 sides.

therefore n=3, substitute as n=3 in the formula above.

Total angle in a triangle = 180 (3-2) = 180 (1) = 180 degrees

The sum of the angles in a triangle must equal to 180°

∠QRS+∠RSQ+∠SQR=180°

80°+29.1°+∠SQR = 180°

∠SQR = 180°-109.1°

The angle SQR = 70.9°
