Answer:

x=52

y=137

Step-by-step explanation:

The angles of a triangle add to 180

Looking at the big triangle

38+90 +x = 180

Combine like terms

128 +x = 180

Subtract 128 from each side

128-128 +x = 180-128

x =52

Then looking at the quadrilateral at the bottom

The sum of the angles is 360

90+90+y-9 +x = 360

180 -9 +x+y = 360

171 +52 +y = 360

223 +y = 360

Subtract 223 from each side

223-223 +y = 360-223

y =137

Answer:

x = 52, y = 137 degrees.

Step-by-step explanation:

x = 180 - 90 - 38

x =  52 degrees   (as there is 180 degrees in a triangle).

As they are the same side inner angles between 2 parallel lines:

x + (y - 9) = 180

52 + y - 9 = 180

y = 180 - 52 + 9

y =  137 degrees.

7^8 divide by 7y =7^6 find the value of y
lisabon 2012 [21]
Answer: y = 7

Explanation:

7^8/7y = 7^6
7^7/y = 7^6
In order for 7^7 to become 7^6 you need to divide by 7

Which mean y = 7

So that:
7^7/7= 7^6
7^6 = 7^6

If A = C + 3A=C+3, B = 2CB=2C, and C = 4C=4, which is the correct order from least to greatest?
kotykmax [81]

Answer:

B, C, A.

Step-by-step explanation:

A = C + 3A = C + 3

A = C + 3

A = C + 3A

C + 3A = C + 3

3A = 3

A = 1

A = C + 3

1 = C + 3

C + 3 = 1

C = -2

B = 2C

B = 2(-2)

B = -4.

So, from least to greatest, B = -4, C = -2, and A = 1.

Hope this helps!
