Hey there!
4(9/4 + 5/7c)
= 4(9/4 + 5/7(-7))
= 4(9/4) + 20/7(-7)
= 4(9/4) - 20
= 9 - 20
= -11
Therefore, your answer is: -11
Good luck on your assignment and enjoy your day!

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
