Help find x values and y values

Mathematics
1 answer:
WINSTONCH [101]3 years ago
7 0

Answer:

x = 15, y = 21

Step-by-step explanation:

We have 2 vertical angles that are equal to each other, and equals (6x - 11).

For right triangle:

(6x - 11) + 81 + (x+ 5) = 180

6x - 11 + 81 + x+ 5 = 180

7x + 75 = 180

7x = 105

x = 15

For left triangle:

(4y - 18) + (6x - 11) + (y +14) = 180

4y - 18 + 6x - 11 + y +14 = 180

5y + 6x - 15 = 180

Substitute x = 15.

5y + 6*15 - 15 = 180

5y + 75 = 180

5y = 105

y = 21

A varies inversely as the square of B. If A is 1 when B is 3, find A when B is 5
RideAnS [48]

Answer:

0.36

Step-by-step explanation:

A= K/B^2

K= A × B^2

K= 1 × 3^2

K= 1×9

K= 9

Therefore if B is 5 then A can be calculated as follows.

K= A × B^2

9= A × 5^2

9= A × 25

9= 25A

A= 9/25

A= 0.36

Hence A is 0.36
