Answer:
22 meters
Step-by-step explanation:
What we know:
Side AB is 7 1/2 m long, Side BC is 2 1/4 m long, and Side DE is 1 1/4 m long.
Saying Sides AH and FG are the same as Sides DE and BC respectively, we can add another 3 1/2 m to the perimeter.
If CD, EF and GH are each 1/3 of AB, then 7 1/2 is added again.
7.5 + (2.5 * 3) * (2.25 * 2) + (1.25 * 2)
7.5 + 7.5 + 4.5 + 2.5
15 + 7
The perimeter is 22 meters.
Answer:
Step-by-step explanation:
There is no such thing as the inverse Law of Cosines. You CAN use the law to find a missing angle, which is found by finding the inverse cos of a ratio. For example, if you have all 3 sides of a non-right triangle and you are looking for the measure of an angle, you would do all the required math, and in the end you would have that cos(x) = some fraction. Take the inverse cos on your calculator of this fraction and get the angle value.
In other words, the Law of cosines can be used to find both a missing side OR a missing angle.
Answer:
6
9
6.48
Step-by-step explanation:
this is the easiest way to solve for percentage:
Where all the percents (except 100) would go in part
and the whole number would go in whole
Then multiply 24 × 25 ÷ 100 = 6
Multiply 60 by 25 then divided by 100 = 9
Then for the last one 9 is what percent of 72
all we have to do is multiply 9 and then convert 72 into a decimal (0.72)
Then 9 × 0.72 = 6.48
2x+5=3x-1
+1 +1
2x+6=3x
-2x -2x
x=5
y=2(6)+5
y= 12+5
y=17
(5,17)
Answer:
6 * 16
Step-by-step explanation:
One pound is 16oz.
Multiply the number of pounds by 16.
6 * 16 = 96
6 pounds is 96oz.
Hope this helps.
