Is the x2 supposed to be squared?
Answer:
Step-by-step explanation:
c + 11 = 20....subtract 11 from both sides
c = 20 - 11
c = 9
and u know that u can check ur answer by subbing it back into the equation
c + 11 = 20
9 + 11 = 20
20 = 20 (correct)
so yes, ur answer c = 9 is correct
Answer:
B. 16.7
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relationship between the side adjacent to the angle and the hypotenuse involves the cosine function:
Cos = Adjacent/Hypotenuse
Filling in the numbers from your diagram gives ...
cos(50°) = x/26
Multiplying by 26 gives x.
x = 26·cos(50°)
x ≈ 16.7
