Answer:
add up all the sides!!
6+3+3+3+5+12+4+6=38
so the perimeter is 38 ft
Answer:
<h3>5 feet</h3>
Step-by-step explanation:
The set up will give a right angles triangle with:
length of the ladder as the hypotenuse h = 13 foot
The distance from the base of the house to the top of the ladder is the opposite side (y) = 12 feet
The distance of the base of the ladder from the base of the house wil be the adjacent side (x)
Using the pythagoras theorem to get x:
h² = x²+y²
13² = x²+12²
x² = 13²-12²
x² = 169 -144
x² = 25
x = √25
x = 5 feet
Hence the distance of the base of the ladder from the base of the house is 5 feet long
The values of x and y are 19 and 14 respectively.
<h3 /><h3>How to determine the length</h3>
Given the hypotenuse = 24
Opposite = x
Adjacent = y
Let's use the sine ratio to find the opposite side
sin of angle = opposite/hypotenuse
sin 54 = x/24
Cross multiplysin 54 × 24 ,= x
x = 19.42
x = 19
To find the adjacent side, we use cosine ratio
cos = adjacent/hypotenuse
cos 54 = y/25
Cross multiply
cos 54 × 24 = y
y = 14
Thus, the values of x and y are 19 and 14 respectively.

Answer:
C. 
, 
Step-by-step explanation:
We have given a diagram of a right triangle. We are asked to find the value of x and y.
We can see that our triangle is 30,60,90 triangle.
The smallest side is the side corresponding to 30 degree angle, that is x. The longer side is corresponding to 60 degree angle, that is y.
Since the measure of smallest side in a 30, 60, 90 triangle is half the measure of hypotenuse. Upon looking at our given triangle we can see that hypotenuse is 
, therefore, measure of x will be,
Now let us find the value of y (longer side) by multiplying the length of smaller side (x) by 
, therefore, the measure of y will be,
Upon looking at our given choices we can see that option C is the correct choice.
5 dozen= 60 doughnuts
3;43-3;27 = 16
So it took him 16 minutes for 48 doughnuts
16÷48=0,3 so one doughnut takes him 30 seconds
60×0,3=19,99=20 so it takes him about 20 minutes for 5 dozens of doughnuts
So it'll be 4;03
