Use the diagram given below to answer both questions b
a
Part A
Which equation could be used to determine the value of ?
+ 2 + 90 = 180
2+2+ 45 = 90
+ 90 = 180
2c + 90 = 360
Part B:
What is the value of 2?
The value of zis

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

ok then what happened.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
