Angle V = 25 degrees. See the attached picture:
X < -1
rearrange➡ 5 + 6 × (x + 4) - (20) < 0
➡ ( 5 + 5 × ( x + 4 )) - 20 < 0
Pull out all of the like terms (factors) ➡ 5x + 5 = 5 ( x + 1)
5 × ( x + 1 ) < 0
divide botg sides by 5
Solve, basic inequality
Subtract 1 frok basic sides
x < -1
Lets name the largest number as x
smallest number is half the largest , therefore its x/2 = 0.5x
then middle number is 3/4 the largest , therefore its 3/4x = 0.75x
the sum of the three numbers are 162
the three numbers added are
x + 0.5x + 0.75x = 162
2.25 x = 162
x = 72
the largest number is 72
then middle number 0.75 x = 0.75 x 72 = 54
smallest number is 0.5x = 0.5 x 72 = 36
answer is - 36,54,72
