Answer:
p/3 is the same as p*1/3 so the third option
Step-by-step explanation:
1. 103-22 = 81
2 10.2-3y+2x is already in simplest form
2 supplementary angles when added together need to equal 180 degrees.
Add:
3x-23 + 2x-12 = 180
Simplify:
5x -35 = 180
Add 35 to both sides:
5x = 215
Divide both sides by 5:
X = 43
Now replace x with 43 in the equation for angle b:
2(43) -12 = 86-12 = 74 degrees
Angle B = 74 degrees
Answer:
75% for number 2 i think number 3 is 70%
