<u>Answer:</u>
Perimeter = 20 units
x = 120°
<u>Step-by-step explanation:</u>
We are given a triangle ABC with known side lengths for all three sides and an inscribed circle.
We are to find the perimeter of triangle ABC and the value of x.
Perimeter of triangle ABC = 2 + 2 + 5 + 5 + 3 + 3 = 20 units
The kite shape at the end is a quadrilateral which has a sum of angles of 360 degrees.
Two out of four angles are right angles and one is 60 so we can find the value of x.
x = 360 - (90 + 90 + 60) = 120°
Answer:
Length = 30
Width = 5
Step-by-step explanation:
So the formula for perimeter is
P = 2L+2W
And we know that:
L = 6W
So then we put in all the information that we do know
70 = 2(6W)+2W
And pop that into a calculator and you get W=5
So now we put that information into L = 6W to get:
L = 6×5
L = 30
Answer:
97 and 1/2 remainder

- 6+ 5x = 6x - 3
move -6 to the other side
sign changes from -6 to +6
-6+6+5x= 6x-3+6
5x= 6x-3+6
5x= 6x+3
move -6x to the other side
sign changes from +6x to -6x
5x-6x= 6x-6x+3
5x-6x= 3
-x= 3
mutiply both sides by -1 to get +x
(-1)(-x)= x , (-1)(3)= -3
Answer: x= -3
