Y=4/5x hope that’s the right answer
Answer:
x = 10√3
Step-by-step explanation:
Because of the right angles, we can use Pythagoras
30² - x² = y² (a) Largest triangle
y² - 20² = h² (b) Medium triangle
substitute y² from (a) into (b)
30² - x² - 20² = h²
500 - x² = h² (d)
x² - h² = (30 - 20)² (c) smallest triangle
substitute h² from (d) into (c)
x² - (500 - x²) = 100
2x² = 600
x² = 300
x = 10√3
Answer:
(6,17)
Step-by-step explanation:
2x+5=3x-1
-3x -3x
-x+5=-1
-5 -5
-x=-6
^divided by -1 on both sides
x=6
y=2x+5
y=(2)(6)+5
y=17
