180 degrees in a triangle. so 180-90-31=59
Answer:

Step-by-step explanation:

Add the fractions since the denominators are the same.


Simplifying the fraction.


The question is simply asking us to create a word problem.
The word problem describing the division expression 3÷1/4 will be:
Given that Annie has 3 oranges and he wants to each orange into quarters, how many quarters will Annie have in total?
Using proportions, the amounts received by each student are given as follows:
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The amounts that each receive are given as follows:
- Ahmed: 6/7 of Ali, hence 6x/7.
- Amir: 1/7 of Ali, hence x/7.
The total amount shared is of Rs 1,400,000, hence we can solve for x as follows:
x + 6x/7 + x/7 = 1,400,000.
2x = 1,400,000.
x = 700,000.
Hence the amounts are:
