(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
step-by-step explanation:
ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t. then add -3.6 + 1.2 which is -2.4
so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
central angle of a triangle has the same measure as its intercepted arc.
