14.14
Step-by-step explanation:
You can find the value of x using the trig ratio Sine = opposite/hypotenuse.
The sin 45 = 10/x. Solve for x.
x= 10/ sin45
x = 10/0.707
x = 14.14
Answer:
2(7) + 5 = 19
Step-by-step explanation:
Okay, so do it like this:
2x+5
x = 7
2(7) + 5
2(7) = 2 x 7
2 x 7 = 14
Now it's 14 + 5
14 + 5 = 19
Your answer is 2(7) + 5 = 19
