Given triangle KLM with two sides given as 45 yd and 20 yd and a 25 degree angle opposite the 20 yd side.
We find the angle made at the opposite of the 45 yd side using the sine rule as follows.
Thus, the third angle is given by 180 - 25 - 71.97 = 83.03 degrees.
We also use the sine rule to find the third side of the triangle as follows.
Therefore, amount of fencing needed to surround the perimeter of the picnic area = 45 + 20 + 46.97 = 111.97 ≈ 120 yds
(P1*V1)=(P2*V2)
P1= 5 atm
P2= 3 atm
V1= 4L
V2=?
(5*4)=(3*V2)
20=3(V2)
V2=20/3 L which is 6.66666667L
Answer:
C. 52 cm
Step-by-step explanation:
A full circle has a degree measure of 360 degrees.
Minor arc DE is intercepted by a central angle of 120 degrees.
120 degrees is 1/3 of 360 degrees, so the length of minor arc DE is 1/3 of the circumference of the circle.
length of minor arc DE = (120/360) * 2 * pi * r
length of minor arc DE = (1/3) * 2 * 3.14 * 25 cm
length of minor arc DE = 52.3333... cm
Answer:
<h3>The answer is ( 4 , - 2)</h3>
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A(2,-5); B(6,1)
So we have
We have the final answer as
<h3>( 4 , - 2)</h3>

Answer:
5
Step-by-step explanation:
mean = sum of all values÷number of observation
= 3+7+5+6+4 ÷ 5
= 5
