Answer:
The perimeter of the figure is 111.46 units
Step-by-step explanation:
Given:
RS = 43
LS = 18√2
A right Triangle is attached to a Rectangle.
A right Triangle is having measure angle 45° , 90°
and Hypotenuse = 18√2
∴ The Third Angle measure will also be 45° {angles Sum property of a triangle}
∴ the right angled triangle is an Isosceles triangle.
∴ Two sides are equal LT = TS
To Find:
Perimeter of figure = ?
Solution:
we have
we Know sin 45 = 1/√2
∴ 
Now ,
ARTL is a Rectangle
∴ opposite side of a rectangle are equal
∴ LT = AR = 18 unit
and AL = RT
But,
RT = RS - TS
= 43 - 18
25
∴ AL = RT = 25
∴ Perimeter of figure = AL + LS + RS + AR
= 25 + 18√2 + 43 + 18
= 86 + 18√2
= 111.455
= 111.46 units
∴ Perimeter of figure = 111.46 units
Remember you can do anything to an equiaotn aslong as you do it to both sides
try to isolae the variable then find 1 of it
50=7x-6
add 6 to both sides
56=7x
divide both sides by 7
x=8
Answer:
2/3 =8/12
Step-by-step explanation:
2/3
Multiply the top and bottom by 4 to get a denominator of 12
2/3 *4/4
8/12
2/3 =8/12
Answer:
0.01875 miles per hour
Step-by-step explanation:
0.75 divided 40
0.01875
The number of miles covered every evening obtujwd using a <em>system of equation</em> is 15 miles.
<u>Let the number of miles per evening</u> = m
- Number of miles per morning = 8 miles
- Total miles covered = 115 miles
<u>Using the expression below :</u>
<em>Number of days(miles per morning + miles per evening) = 115 miles </em>
5(8 + m) = 115
40 + 5m = 115
5m = 115 - 40
5m = 75
m = 75 / 5
m = 15 miles
Therefore, the Number of miles covered per evening is 15 miles.
