Tell whether the triangle with each set of side lengths is a right triangle. 0.9, 1.2, and 1.5

7, 10, and 15

3.1, 5.7, and 7.1

1, 2.4, and 2.6

answer: 59

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
