In order to use the Law of Sines, EF has to be the included side. Therefore, we need to calculate angle F which is 72 degrees.
side f / sine (F) = side d / sine (D)
side f / sine (72) = side 24 / sine (45)
side f = sine (72) * 24 / sine (45)
side f = 0.95106 * 24 / .70711
side f (DE) =

answer is C
Answer:
x=22
Step-by-step explanation:
angle RTS = 5x-40 (isosceles triangle)
angle RTS + angle STU = 180 (straight line)
so 5x-40+5x = 180
10x = 220
x=22
Answer:
yes it can if its a negative ex like x-1 if you plot this ur line will be horizontal.
Step-by-step explanation:
Step-by-step explanation:
a=31
b=27
A = 46 degree
now, Area of ️ABC =ab siny÷2
=31×27 sin46÷2
=301.04371 .
Answer:
$10p + $ 2.99 = $32.99
Step-by-step explanation:
I got this because he got multiple pizzas that are each $10, but we don't know how many there are, so I put $10p together.
He also pays $2.99 as a delivery charge.
And I ended it with the equation equaling $32.99 because that is the total he paid.
