The walls are vertical so the angle opposite X would be a right angle which is 90 degrees.

X would be 180 - 90 - 35 = 55 degrees

X and 2y - 5 are complementary angles which add together to equal 90:

2y - 5 + 55 = 90

Simplify:

2y +50 = 90

Subtract 50 from both sides:

2y = 40

Divide both sides by 2:

y = 20

Answer:

x= 39 degrees

y= 20 degrees (if incorrect, try 15 degrees)

<u>Step-by-step explanation:</u>

To get x:

Angle RED and Angle YELLOW are alternate angles meaning they're the same. Then, get y on its own by adding five (or subtracting, sorry I couldn't read it) and dividing by 2. Here you get 20 degrees (or 15 if you had to subtract).

To get y:

Angle RED and Angle BLUE are corresponding angles, also meaning they're the same. This means it is also 39 degrees.

Hope this helped!

So you take 2 hours and multiply it by 5 cause you get $5 per hour. Then multiply 6.25 by 5. Add those together to get your answer!! So 5x2= 10. 6.25x5= 31.25. THE ANSWER SHOULD BE 41.25!

HELLO. I NEED HELP ON A HANDFUL OF QUESTIONS. PLEASE HELP. ​

Question 7: $3945

78,900÷100×5= 3,945

or 789,00×0.05= $3,945

Question 8: I think it may be $675.46 ( but I'm not sure)

$1010 is her annual insurance premium so to find one month we need to divide $1010 by 12

$1010÷12= $84.20

also her annual real estate tax is $938 and to find one month we need to divide this by 12 as well.

$938÷12=$78.20

and in order to find out her combined monthly payment we need to add them all together

$513.12+$84.16+$78.16= $675.46

Question 9: is False

Question 10: I don't know

Hope this helps

Esi says that the value of z when z^2 = 80 does not belong in either of these categories since z must be greater than 8.
Anettt [7]

Answer:

9

Step-by-step explanation:

if z=8 then z^2 would be 64, which is not equal to 80

iz z=9 then z^2 would be 81, which is closer to 80 than 64

therefore, 9 is the whole number than z would be closest to
