Answer:
4.88
Step-by-step explanation:
sinA=opposite/adjacent
sin24=x/12
12(0.40673664307)=x
x=4.88083971691
Answer:
GH ≈ 104.3 ft
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos20° = 
= 
= 
Multiply both sides by GH
GH × cos20° = 98 ( divide both sides by cos20° )
GH = 
≈ 104.3 ft ( to the nearest tenth )
Answer:
Step-by-step explanation:
To solve this system of equations, let's first find the value <em>y</em>. We can replace the x in the second equation with 11 + y, since we are told in the <em>first</em> equation that x is equal to 11 + y. So, let's replace x:
2(11 + y) + y = 19
22 + 2y + y = 19
22 + 3y = 19
3y = -3
y = -1
And look at that - we've found our y-value! Now, we can replace the y in the <em>first</em> equation with -1 to find the value of x.
x = 11 + (-1)
x = 10
So, the solution to this system of equations is (10, -1). Hopefully that's helpful!
The first two are correct
Is it y=mx+b because if it is then plug the numbers in
