Answer:
33 ft.
Step-by-step explanation:
First, you would put the x at the opposite side, because that's what the problem is asking for, the distance between the ground and the top of the ladder. Then, because it is opposite and adjacent, you use tangent to solve the problem. Equation: tan(70)=x/12, tan=opp/adj. Then, cross multiply and get x=12(tan(70)), and then multiply to get 32.97 and round up to 33 ft.
(hope this helps!!)
Jane = x years
Tom = x+8
*5 Years Ago
Jane= x-5
Tom= (x+8)-5=>x+3---------------------------
x+3=3(x-5)<span>x+3=3x-15
3x-x=18
2x=18
x=9
Jane = 9 years
Tome = 9+8 = 17 years</span>
Answer:
x = 1, y = 2
Step-by-step explanation:
Original equations:
Substitute y and solve for x:
Plug in x to solve for y:
x = 1, y = 2
Note: You can also substitute x and solve for y, then plug in y to solve for x. I did not do that here.
