Answer:
a. ∆BAC & ∆DEC
b. they have a vertical angle because they both share c, and <a = <e. If two angles are congruent, the third must be congruent as well.
c. √90 = 3√10
Answer:
the ratio of horizontal change compared to vertical change
Step-by-step explanations
slope = difference of y/ difference of x
rise (y) over (/) run (x)
change in y over change in x (y/x)
horizontal change (x): to vertical change (y) WRONG

Answer:</h3>
A) Quadrilateral
<h3>
Explanation:</h3>
Here the figure is not a rectangle and parallelogram as it does not have two parallel sides. The figure cannot be considered as a trapezoid as the shape does not have either one parallel side. All the sides are in its unique form. Though it has four sides so it can be considered as a Quadrilateral.
Answer:
c, 65 + 28H > 250 Anand can only afford 6 hours of plumbing
Step-by-step explanation:
When we look at all of the inequalities, we can narrow down to two. Answer c and answer d. We narrow down to these two because the plumber charges a 65 dollar initial fee. That means no matter what you need to pay the plumber 65 dollars. Then you also have to pay the plumber 28 dollars at an hourly rate. that can be said as 28H. If we look at all of the inequalities, we can say that c or d would be the correct answer because the 65 dollars is the initial value, and the plumber is getting 28 dollars every hour. Now Anand also says that he doesn't want to pay more than 250 dollars. That must mean that 65 + 28H must equal less than 250. So our new equation is 65 + 28H < 250. So for the first part, C is the correct answer. Now for the second, how many hours can Anand afford? To figure out the second part of the question we have to solve the inequality. So we subtract 45 from both sides. After doing that, we divide 28 from both sides. H is going to equal to 6.607... But we can round this decimal to 6 and our answer is Anand can afford 6 hours of plumbing to make sure he doesn't go over 250 dollars.
