Answer:
c = 105 degres
Step-by-step explanation:
When two lines cross like that and form an x, the opposite sides are equal (so the angle below the 75 degree one is also 75 degees). Using this, you can figure out the rest.
If both the top an bottom are equal, you know that 150 degres are taken (75+75) and you know that there can only be 360 degres in total here, so you subtract 150 from 360 and get 210. Now you know that the last two sides together are 210, and since they are equal, you divide it by two to get 105 degrees.
34+50+50+50-60+22
You add everything except 60 because deposits mean add money to the account. You subtract 60 because a withdrawal is taking money out of the account. There are three 50s because you deposit $50 each day for 3 days.
