Answer:tan 30 = 5/b
Step-by-step explanation:
From the diagram line BC is opposite to the angle 30 and line AC is adjacent to that same angle
From trigonometric ratios
Tan 30 = opposite /adjacent
Answer:
94 ft of paper
Step-by-step explanation:
This is asking for the border, or, the perimeter of the classroom. You simply add all sides together.
You multiply each side by two as to make up for the missing sides of the classroom.
22 x 2 + 25 x 2
or
22 + 22 + 25 +25
44 + 50
94 ft.
Answer:
60 ft, 120 ft, 182 ft
Step-by-step explanation:
Hi there,
To find the perimiter of a polygon, you need to add of all of the sides.
So, let's do that:
x + 2x + 3x+2
Since we are given the perimeter, we make what we just did above, equal to the perimeter
x + 2x + 3x +2 = 362
Combine lke terms...
6x + 2 = 362
Subtract 2 from both sides to start to isolate the variable...
6x = 360
Divide both sides by 6 to isolate x...
x = 60
But we're not done yet...
The length of the first side is 60 ft, the length of the second side is 2*60 which is 120 ft, and the length of the third side is 3*60 + 2 which is 182 ft.
Let's check...
Does 60 + 120 + 182 = 362?
362 = 362
Our answers are right
Hope this helps! Stay safe!

You can solve it with the numbers you already have.
so, 23 - 15 = 8
so 15 + 8 = 23
b is 8 (:
