list the angles of triangle DEF in order from smallest to largest measure if DE equals 7 EF equals 9 and DF equals 3
1 answer:
When you illustrate the problem, an image like that shown in the picture is formed. You are asked to order the angles in increasing order. Since, it did not ask for the values, we don't have to solve it.
Note that the larger the angle, the larger its opening, thus its opposite side would be larger also. Using this analogy and referring to the picture, the order of angles should be: Angle E < Angle F < Angle D

Answer:
volume of the solid is 3.180
Step-by-step explanation:
given data
line x + y = 2
parabola x2 + y = 4
to find out
the volume of the solid
solution
we draw a graph between line and parabola as show in fig given below attach
line cut at (-1,3) and (2,0)
so the length of diameter is ( 4 - x²) - (2 - x)
and radius of this semi circle will be ( 4 - x² - 2 + x ) /2
radius = (-x² + x + 2 ) /2
and r(x) will be = (-x² + x + 2 ) /2
and A(x) will be = π ( r(x)² ) /2
we will integrate from -1 to 2
=
=
= 81π / 20
volume of the solid is 3.180
