Answer:
Step-by-step explanation:
<C = ?
a = 22
b = 20
c = 18
Formula
c^2 = a^2 + b^2 - 2*a*b* cos(C)
Solution
18^2 = 22^2 + 20^2 - 2*22*20*cos(C)
324 = 484 + 400 - 880*cos(C)
324 = 884 - 880*Cos(C)
-560 = - 880 * cos(C)
-560 / - 880 = cos(C)
0.63636 = cos(C)
C = cos-1(0.63636)
C =50.48
Answer:
We have, 48% × x = 12
or,
48
100
× x = 12
Multiplying both sides by 100 and dividing both sides by 48,
we have x = 12 ×
100
48
x = 25
If you are using a calculator, simply enter 12×100÷48, which will give you the answer.
