(a) Is 1.25 each.
(b) Is 1.22 each.
(c) Is 1.24 each.
(d) Is 1.20 each.
The correct answer and cheapest per unit, is (d).
Angle c is equal to 34 degrees. Explanation: if a=73 and b is the same as a. 73+73=146, the sum of the interior angles of a triangle is 180 degrees so 180-146= 34 degrees. Angle c is 34 degrees.
Answer:
Step-by-step explanation:
Given
We need to find the expression for 
in simplest form. Hence we plug in the substitutions into the expression and simplify:
2nd answer choice is right.
Based on this information we can conclude that in one hour, Oliver and his sister would get all of the windows washed. This means that it would take 5/6 hours which is equal to 50 minutes) for them to get all of the windows washed.
<h3>What is information?</h3>
Information is defined as the content of a message which is passed from a source to its receiver.
The number of hours it takes for Oliver to wash the house windows = 2 hours, so in an hour = 1/2
The number of hours it takes his sister to wash the same house windows = 3 hours, so in an hour = 1/3.
To calculate for one hour for both would be addition of the derived fractions;
= 1/2 + 1/3
= 3+2/6
= 5/6
When converter to minutes, multiple by 60;
= 5/6 × 60
= 300/6
= 50 minutes.

37+53=90 so 180-90=90
x=90
x= 180-(37+53)
x= 90 ✅
