Answer:
x = 93°
Explanation:
1) Isolate the x
To isolate the x in (x-73) all you need to do is get rid of the 73 and add it onto other terms in the question that are similar
- The term similar to -73 would be 67 so add them...
- -73 + 67 = -6
2) Figure out x
Not that all you have are x's you would know that both of them have to be equal. Therefore you need to...
- subtract 180 from -6 as it is the only number left 180 - (-6) = 186
- As there are 2 x's you had to divide you answer by 2 186 ÷ 2 = 93
3) Check your answer
To check if your answer works you need to work your way backwards...
- x is 93 so... 67 + 93 = 160
- 93 - 73 = 20
- 160 + 20 = 180
- And it works!
Hope this helps, have a great day!!
