Associative Property states that grouping symbols does not affect the outcome. This property works for Addition and Multiplication:
2 + (3 + 4) = (2 + 3) + 4
6 • (5 • 4) = (6 • 5) • 4
So first, here, subtract 17 from both sides.
17 + 3f = 14
- 17 -17
3f = -3
Then divide both sides by 3
f = -1
Using the properties of arcs and inscribed angles, B is 110/2=55.
The opposite angles of a quadrilateral are supplementary so you can set them equal to 180.
If there was more information given then i could find the exact values.
Hope this helps :)
Answer:
x=18 degrees
Step-by-step explanation:
since this is a triangle, you know that the three angles added up equal 180 degrees. since it is a right triangle, 25+3x+11=90 (the right angle=90). then you just solve for x: 3x=54, x=18
