Answer:
F=73.74 degrees
Step-by-step explanation:
sin=opposite/hypotenuse
opp=24 hyp=25
sin(F)=24/25 (to find angle have to use inverse sin)
sin-1(24/25)=73.74
Answer:
x = 1
y = -1
Step-by-step explanation:
y = 3x + 4y
3x + 3y = 0
So, we have 2 equations that are
3x + 3y = 0
x + 2y = -1
Times the second equation by -3
3x + 3y = 0
-3x - 6y = 3
-3y = 3
y = -1
Now put -1 in for y and solve for x
x + 2(-1) = -1
x - 2 = -1
x = 1
Let's check
1 + 2(-1) = -1
1 - 2 = -1
-1 = -1
So, x = 1 and y = -1 is the correct answer.
