Answer:
nj +k = p
Step-by-step explanation:
n = (p-k)/j
Multiply each side by j
nj = (p-k)/j *j
nj = p-k
Add k to each side
nj +k p-k+k
nj +k = p
Answer:
105 degrees
Step-by-step explanation:
To start this think about what you know has to be true about this:
- Angle WRQ and PRQ when added will equal 180
- Triangle PRQ when all the angles are added will equal 180
- We have to find x to find what the angle measure of angle WRQ is
So let's start to write an equation:
Let's say angle PRQ is y.
20x + 5 + y = 180
27 + y + 14x + 8 = 180
Now let's use substitution to solve for y:
20x + 5 + y = 180
subtract 5 from both sides:
20x + y = 175
subtract 20x from both sides:
y = -20x + 175
Let's now plug in y to our other equation:
27 + (-20x + 175) + 14x + 8 = 180
now combine all like terms:
-6x + 210 = 180
now solve for x:
subtract 210 from both sides:
-6x = -30
divide both sides by -6:
x = 5
Now that we have x, let's plug it in for the equation of angle WRQ:
20(5) +5
Simplify:
105
Hope this helps!
Answer:
49
Step-by-step explanation:
Complementary angles always add up to 90 degrees, so make and equation. First, say that angle ABC and angle QRS add up to ninety degrees. Substitute the values to get 41 degrees plus angle QRS equals 90 degrees, and once you subtract 41 from both sides, you get angle QRS equals 49 degrees.
Hope this helps. :)

Answer:
x = 4
Step-by-step explanation:
The figure is a rhombus when the sides are the same length.
21 -x = 2x +9
12 = 3x . . . . . . . . add x-9 to both sides
4 = x . . . . . . . . . . divide by 3
The difference in the volume of bedroom door in the house taken the length and width into consideration will be 120 inches³.
<h3>How to calculate the bedroom door?</h3>
It should be noted that the volume of a door is simply gotten by multiplying the length by width.
Let's assume that the width is 20 inches. Therefore, the difference will be:
= (36 × 20) - (30 × 20)
= 720 - 600
= 120 inches³
