As fraction it would be 6/30 reduced 1/5 and as percentage 20% so 20% of the students were off.<span />
Divide the number of respondents saying it was useful by the total number
63/85 = 0.74
2,000
10,000 divided by 5 = 2,000
Answer:
∠TUY = 120°
Step-by-step explanation:
There are two rules you can apply here:
1) The sum of the angles inside a triangle is 180°. This means that ∠SUT = 180° - 70° - 50 ° = 60°
2) A vector coming out of a line two angles between itself and the line, and they add up to 180° as well. This means that ∠TUY = 180° - ∠SUT. So ∠TUY = 180° - 60° = 120°
So the missing angle one hundred and twenty degrees.
