Answer:

A= 69 degrees

Step-by-step explanation:

if all those angles equal a total of 180 degrees then all you need to do is add the angles your given which in this case is 21 and a 90 degree angle which would equal 111 degrees, then subtract 111 from 180 and that would be the answer to the missing angle, which is 69 degrees.

21 + 90 = 111

180- 111 = 69

D.) It is not correct because the second number tells you how far to go up or down, not across.

Second number represents y-coordinates, so they are the points in vertical direction, in that case you can't move in x-axis which is horizontal.

Hope this helps!

     We can make this an equation, lets start with how much money he has. Since he bought the motorbike he lost 2,000, then sold it and received 2,500. The 2,000 cancels out but he still has 500. Now that he bought it for 2,200 we subtract 2,200 from 500 and get -1,700. Then finally, he sold it for 2,000 so we add that to -1,700 and get 300. His total profit was $300.

-2,000 + 2,500 = 500
500 - 2,200      = -1,700
-1,700 + 2,000 = 300

BlackZzzverrR [31]

Answer:

10.39 or 10.4

Step-by-step explanation:

Since this is a right triangle, you have the formula a squared +b squared = c squared where a and b are the legs and c is the hypotenuse. You plug in the values and you should get sqrt of 108 for x.

What is the solution of x2+49 = x+5?
nikklg [1K]

Answer:

x = 12/5

Step-by-step explanation:

take the square of both sides

(x^2+49) = (x+5)^2

x^2 + 49 = (x+5) (x+5)

x^2+49= x^2 + 10x + 25

10x + 25 = 49

10x = 24

x = 12/5
