Answer: 55.4 mins
Step-by-step explanation:
pragnesh and qazi = 2hrs
pragnesh and roghui = 3hrs
qazi and roghui = 4hrs
this means for every 1 hour they wold paint.
pragnesh and qazi =
half of the fence
pragnesh and roghui = 
qazi and roghui =
quarter of the fence
time taken when they all work together

= 
= 
= 0.9231 × 60(mins)
= 55.4 mins
Answer:
137°
Step-by-step explanation:
Basically, its the reverse of question 1.
With angle x, you can find out that the opposite angle is 360 - 106 = 254°
the angle is twice the size of angle y as said in the corcle theorems.
254 divided by 2 = 137°
(please correct me if im wrong, i feel like im missing something)
2.6 rounds to 3, and 0.33 would round to 0.50. Adding 3 and 0.50 together would equal to 3.50. 59 and 3.50 are no where near to each other which concludes Minh is incorrect.

Answer:
C.
Step-by-step explanation:
The two angles are better known as corresponding angles, and since the two lines are parallel, then the angles must be congruent. This means x = 115 degrees.
C. The values of x is 115 because the two angles shown are congruent.
<u>Why the other answers are wrong:</u>
A & B are wrong because it states the two angles are supplementary, but supplementary angles have to add up to 180 degrees and 115+115 is 230 not 180.
D is wrong because there's no logical explanation to why you would subtract 90 degrees from 115 to solve for x.
