We are given that BA is perpendicular to BD, so that must mean that <em>m∠ABD </em>is a right angle, or 90º. This means: (8x - 10) + (4x + 52) = 90º, since both of the angles add up to become a right angle. We have to solve for x in order to find <em>m∠CBD.</em>

<u>PART 1</u>
<em />
<em /><em />
Equation: (8x - 10) + (4x + 52) = 90
Let's add the like values together first.
Let's subtract 42 from both sides of the equation to isolate the variable we are solving for, x. Our goal is to isolate it completely to get a value that is equal to x.
Divide both sides by 12 to get our final answer for x.
<u>PART 2</u>
<u></u>
Now that we have x, we simply plug it into our equation for <em>m∠CBD. </em>

Multiply 4 and add 52.
Answer:
1340
Step-by-step explanation:
I think this means 32% of 4200
(32/100) * 4200 Multiply 32 * 4200
134400 / 100 Now divide by 100
1340 The last 2 zeros go when dividing by 100

Answer:
A. 4/24
Step-by-step explanation:
If you convert to a common fraction which is 24. Then you get 16/24 - 12/24= 4/24. And if you simplify you can get 1/6. Have a great day, let me know if correct, and hope this helps!
