d. 6, 12, 13

3. do the side lengths of 8, 10, and 13 form a right triangle?

4. Determine if ▼ABC is a right triangle if AB=36, AC=48 and BC=60

1. a. no.

b. no.

c. no.

d. yes.

2. a. no.

b. no.

c. yes.

d. no.

3. no it does not.

Step-by-step explanation:

im not sure about number 4 but i hope the others helped!

(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
