If two angle measurements are 53° and 70,° what must the third angle measurement equal to form a triangle?Please help

57 degrees

Step-by-step explanation:

in a triangle the three interior angles always add to 180°

if you add 53 and 70 you get 123

to find the missing angle you would subtract 180 from the two numbers added

180 - 123

so 57 degrees

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.
