A quadrilateral has four sides meaning it will also have four angles that all add up to 360 degrees. Since you already know three of the angles (60, 45 and 100) you just need to add them up and subtract the answer from 360.
60+45+100=205
360-205=155
So the fourth angle is 155 degrees

Answer:
C
Step-by-step explanation:
I've done this and I got it right
X = 3
How?
You have to equal both sides together.
3x + 1 = x + 7
Subtract x from both sides.
2x + 1 = 7
Subtract 1 from both sides.
2x = 6
Divide 2 from both sides.
X = 3
Answer:
40
Step-by-step explanation:
So if you add 5 to 75 you get 80 so that means there were 80 matches all then you divide 80 by 2 and voila 40!
