Answer:
10-35-45 and 5-17.5-22.5
Step-by-step explanation:
Answer:
x=2y-8
We use the substitution of x in the second equation
2*(2y-8)+3y= -2
4y-16+3y=-2
7y-16= -2
7y= -2 +16
7y=14
y=14Ș7
y=2
so x= 2*2 -8
x=4-8
x=-4
the solution is (x,y)=(-4, 2)
Step-by-step explanation:
Y=(-19x+5)/4 thats your answer
Tan 44° = x/140
x = 140 tan 44°
x approx = 140 * 0.9657 = 135.198
Remember, we need to add another 4 feet, so the answer would be 139.198 feet
