4.1*4.1*6=100.86 inches^2
We have to know the angle that is not labelled. (lets call it y)
9x + y= 180
and the sum of the angles of a triangle is 180
5x + (9+x) + y=180
2 simultaneous equations
Answer:
16.5
Step-by-step explanation:
The relationship between x and y is that y is just x+3.5. So if x is 13, then y is 13+3.5 which is 16.5.
Step-by-step explanation:
L.H.S=(1-cosB)(1+cosB)
=(1-cos^2B). {using (a+b) (a-b)=(a^2-b^2)in second step}
=sin^2B
=1/cosec^2B
Therefore,L.H.S=R.H.S proved
Answer:
x=$59.69
Step-by-step explanation:
We can create a proportion to find the answer.
Thus, we get 4 hr/$39.79=6 hr/$x.
Cross multiplying gives us 4x=238.74, and solving for x gives us $59.685.
We can round to $59.69.
