FIRST STEP:

2x + 3x + 5x = 180

10x = 180

x = 18

SECOND STEP:

2*18 = 36

3*18 = 54

5*18 = 90

36:54:90

Answer:

let ratio be 2x,3xand 5x

Step-by-step explanation:

2x+3x+5x=180(sum of interior angle of triangle)

10x=180

x=180/10=18

:.required angle

2x=2×18=36

3x=3×18=54

5x=5×18=90

Solución 1: 2(x) + 3(y) = 80
solución 2: 3(x) + 2(y) = 70

3(y) + 2(x) = 80
2(y) + 3(x) = 70

2y = -3x + 70
y = -3x÷2 + 35

2x + 3(-3x÷ 2+35) = 80  
-5x÷2 = -25  
-5x = -50

5x = 50   
x-intercept: 10 
x = 10  
y = -3x÷ 2+35

  y = -(3÷2)(10)+35 = 20 

x-interpcet: 10
y-intercept: 20
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
solución: x - 8y = 0
solución x + 4y = 480

-8y + x = 0
4y + x = 480

x-intercept (solución 2)
x = -4x + 480

x-intercept (solución 1)
4y + 180 - 8y = 0
-12y = 480

y-intercept: 40
x-intercept: 320

Answer:

Formula to find height when given diameter and slanted height

\sqrt{s { }^{2} }  - r {}^{2}

First find the radius

24÷2=12

Next square the radius

12²=144

Next square the slanted height

20²=400

Now find the square root of both

\sqrt{400 - 144}

=16ft
