Find the value of x.

Stels [109]

Answer:

x=136

Step-by-step explanation:

The sum of the angles inside a quadrilateral add to 360, so

79+55+110+x=360

Combine like terms

224+x=360

Subtract 224 from both sides

x=136

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.

To find the percentage always multiply whatever decimal number you have by 100% <span>
1) 5 + 8 + 12 = 25 (total number in bag)
5/25 x 100% (because you're trying to find probability of red)
= 20%

2) 5 + 8 = 13 (# of red AND blue)
13/25 x 100% (divide out of the total)
=52%

3) 5/25 = 0.2 x 12/25 = 0.48 (find probability of drawing red and green)
0.2 x 0.48 x 100%
= 9.6%

4) 10 + 12 + 28 = 50 (to find total number of trials)
28/50 x 100%
= 56%

5) 5 x 7 (number of sections on first spinner multiply by # of sections on second spinner)
= 35</span><span>Its B 20%
