Step one know that across from 128 is 128 because of vertical angles
step two a straight line =180 so 128 -180 = 52
step three know you know 3k+4=52 so subtract 4 from 52 and that gives you 48 then divide by 3 to find k and 48/3 is 16
so k +16
because 16x3 is 48 then add 4 which is 52 and 52 plus 128 is 180

If x€{-2,-1,0,1,2,3,4,5} find the solution set 7-x&gt;0 ii 3-4x&gt;-2 vi 3x+4&gt;-2​
maw [93]

Answer:

i) {-2 , -1 , 0 , 1  ,2 , 3 , 4 , 5}

ii) {-2 , -1 , 0 , 1}

iii) {-1 , 0 , 1  ,2 , 3 , 4 , 5}

Step-by-step explanation:

i) 7 - x > 0

⇔ 7 > x

⇔ x < 7

⇔ x ∈ {-2 , -1 , 0 , 1  ,2 , 3 , 4 , 5}

____________________________

ii) 3 - 4x > -2

⇔ 3 + 2 > 4x

⇔ x < 5/4

⇔ x ∈ {-2 , -1 , 0 , 1}

____________________________

iii) 3x + 4 > -2​

⇔ 3x  > -2​ - 4

⇔ 3x  > -6

⇔ x  > -6/3

⇔ x  > -2

⇔ x ∈ {-1 , 0 , 1  ,2 , 3 , 4 , 5}

Your sister says the horizontal measure from her to the rock wall is 5.5 feet, while the horizontal distance is 13.42 feet. What
denis-greek [22]

Answer:

12 feet

Step-by-step explanation:

Given in the question,

horizontal distance from sister to rock wall = 5.5 feet

diagonal distance from sister to rock wall's peak = 13.42 feet

<h3>To find the height </h3>

As we know this figure make a right angle triangle, so we will apply pythagorus theorem

hypotenuse² = height² + base²

13.42² = height² + 5.5²

13.42² - 5.5² = height²

149.85 = height²

height  = √149.85

height  = 12.24 feet

Approximate height of her rock wall to the nearest tenth =  12 feet
