Free Brainlisest to However gets it right. What is the third angle of a right triangle if one of the angles measures 51.1°?

m∠3 = 38.9°

Step-by-step explanation:

If all three angles of a triangle adds up to 180° (Triangle Sum Theorem), it is a right angle (meaning that one of the angle measures is 90°), and m∠1 = 51.1°, then:

m∠1 + m∠2 + m∠3 = 180° (Triangle Sum Theorem)

51.1° + 90° + m∠3 = 180° (Substitution Property of Equality)

141.1° + m∠3 = 180° (Addition Property of Equality)

m∠3 = 38.9° (Subtraction Property of Equality)

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
