The blue print has a scale of 1:20. So every 1 inch represents 20 inches of the actual size. so 3 inches represents 20*3 of the actual table = 60 inches
12 inches is 1 feet
so 60 inches =60/12 = 5 feet
The correct answer is 5 feet.

▹ Answer
<em>(-2, 1)</em>
▹ Step-by-Step Explanation
4x + 3y = -5
-2x + 2y = 6
4x + 3y = -5
x = -3 + y
4(-3 + y) + 3y = -5
y = 1
x = -3 + 1
x = -2
(x, y) = (-2, 1)

Heya !
Given expression -
Subtracting 25 both sides ,
Dividing by 3 on both sides ,
Therefore ,
The value of cos(A+B) is 36/325.
<h3>What is Trigonometry?</h3>
The branch of mathematics concerned with specific functions of angles and their application to calculations.
Given:
cos(A)=−5/13
sin(B)=7/25
Now Using identity,
sin²A + cos² A= 1
sin A= √1 - cos² A
sin A = √1- 25/169
sin A= √144/169
sin A= 12/13
Again,
sin²B + cos² B= 1
cos B= √1 - sin² B
cos B = √1- 49/625
cos B= √576/625
cos B= -24/25
Now,
cos (A +B) = cos A cos B - sin A sin B.
= -5/13* (-24/25) - 12/13* 7/25
= 120/325 - 84/325
= 36/325
Hence, the value of cos (A + B) is 36/325.
