<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- Triangle = 180°
- x = 180 - 79 - 35
<u>Work:</u>
- x = 180 - 79 - 35
- => x = 66
Hence, <u>the size of x is 66°.</u>

Answer:
It would take 25 minutes for Patrick to complete the project alone.
Step-by-step explanation:
They did the project in 20 minutes, that is, 100% of the project, so:
In which x is the percentage that Patrick worked and y is the percentage that Stewart worked.
Patrick works four times as quickly as Stewart, so x = 4y.
So
-----------
Patrick did 80% of the project in 20 minutes. We can solve this problem by a simple rule of three, in which the time it would take for him to complete the project alone is 100%. So
20 minutes - 0.8
x minutes - 1
It would take 25 minutes for Patrick to complete the project alone.
