Answer:
x equals 3.00cm
Step-by-step explanation:
Use Pythagoras' Theorem.
a = (14x-45)
b = (16x+27)
c = (25x)
Plug in the variables above into Pythagoras' Theorem that is, a^2+b^2=c^2.
Solve the resulting quadratic equation and reject the negative answer as length is always positive.
1] 0.23
2] both are same
3] 20/100 *80= 16
x/5 = 6/15
15x = 30
x = 2
answer
x = 2 ft
y/10 = 6/15
15y = 60
y = 4
answer
y = 4 ft
Multiply the top one by 3 for x, so you can eliminate x and find y
then plug in the y into one of the equations to find x
Answer:
2x-4 = -8
Step-by-step explanation:
