Given,
2x - 1/2 = 3 - x
2x + x = 3 + 1/2
3x = 7/2
3x = 3.5
x = 3.5/3
x = 1.167
It is 50 degrees.
Since you already know two are 90 and 40 add them together and you get 130.
A triangle has 180 degrees so minus 130 from that
180-130=50

Answer:
14 feet and 5 inches
Step-by-step explanation:
11 feet + 2 feet= 13 feet
9 inches + 8 inches = 17 inches
17 inches = 1 foot and 5 inches
13 + 1 = 14 feet
5 inches + 0 inches = 5 inches
Total envelopes: 3 + 1 + 3 + 2 = 9 with a total of 3 green ones.
Probability of picking green first: 3 out of 9 = 3/9 = 1/3
There are 8 envelopes left, with 2 green ones.
Probability of picking a green one is 2 out of 8 = 2/8 = 1/4
There are 7 envelopes left and 1 green one.
Probability of picking green is 1 out of 7 = 1/7
Probability of picking all 3 = 1/3 x 1/4 x 1/7 = 1/84
