Find the value of each variable. What are x and y ?

Step-by-step explanation:

since 105 + z is a straight line we know it equals 180 so we can use this equation

180 = 105 + z

simplify

75 = z

the since we know that all quadrilaterals equal 360 degrees we can add our two given number and z then subtract from 360:

102 + 85 + 75

= 262

now subtract

360 - 262

= 98

y = 98

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
