Answer:
12.66 
Step-by-step explanation:
Given the dimensions of the room are 
=
and 
=
.
The area of the room =
Area=
Area=72.33
The area of the carpet=85
The area of carpet left= Total area of carpet - the area of the room
The area of carpet left= 85-72.33=12.66
2 - 2 x 3 + 3
= 2 - 6 + 3
= -4 + 3
= -1
If you are looking forward to adding them together you will get 145. Just need to know if this questions had options?
The height has to be 4, 5, or 6, so the width would be 15, 12, and 10 respectively.
4*15=60
5*12=60
6*10=60
These are the only whole numbers between 4 and 6, as whole numbers are non-decimal numbers greater than or equal to 0
Using supplementary angles, it is found that the measures of the angles are given as follows:
<h3>What are supplementary angles?</h3>
Supplementary angles are two angles whose sum is of 180º.
An interior angle is supplementary with it's exterior angle, hence:
m<a + 150º = 180º -> m<a = 30º.
The sum of the three interior angles of a triangle is of 180º, hence:
30º + m<b + 60º = 180º
90º + m<b = 180º
m<b = 90º.
