Answer:
a = 4.949
b = 4.949
c = 7
Step-by-step explanation:
c ( hypothenuse ) = 7
to find a, use sine
Sine =
Sine 45 =
sine of 45 is 0.707
0.707 =
multiplt 7 on both sides:
0.707 x 7 = x 7
a = 4.949
to find b, use cosine
Cosine =
Cos 45 =
cos of 45 is 0.707
0.707 =
multiply 7 on both sides:
0.707 x 7 = x 7
b = 4.949
