Answer: 4/3 hours or 1 1/3 hours
Step-by-step explanation:
From the question, we are told that two mechanics, Martin and Gordon, are working on your car. Martin can complete the work in 4 hours, while Gordon can complete the work in 2 hours.
Since Martin can complete the work in 4 hours, that means in 1 hour, he will do 1/4 of the work.
Since Gordon can complete the work in 2 hours, that means in 1 hour, he'll do 1/2 of the job.
When they both work together, we will add their fraction of work done in one hour together. This will be:
= 1/4 + 1/2
= 3/4
This means that both of them will do 3/4 of the job in one hour. Then to get the time taken to get the whole job done, we divide 1 by 3/4. This will be:
= 1 ÷ 3/4
= 1 × 4/3
= 4/3 hours
= 1 hour 20 minutes.

3.4+0.4+4.17=7.97 you just have to try different combinations of different numbers with the decimals.
I believe it is opposite angles.. as a rhombus has two pairs, which combined with their 2 pairs of equal segments gives you opposite angles that are equal
