find the area of the triangle given a = 24, b=40, and C= 55°. Round your answer to the nearest tenth. ​
prohojiy [21]

Answer:   393.2 units²

<u>Step-by-step explanation:</u>

Since you know the length of two sides and the measure of the included angle, you can use the following trig formula:

A=\dfrac{1}{2}ab \sin C

Given: a = 24, b = 40, C = 55°

A=\dfrac{1}{2}(24)(40) \sin 55^o\\\\.\quad =480\sin 55^o\\\\.\quad =393.2

The area of a rectangular playground enclosure at francis lewis hw is 500 square meters. the lenght of the playground is 5 meter
Alex Ar [27]
A=L*W
L=W+5
A=(W+5)W
500=W²+5W
W²+5W-500=0

W=(-5+/-√(25+4*500))/2=(-5+/-√2025)/2=(-5+/-45)/2
we are going to take only positive value, so W=(-5+45)/2=20
L=W+5=20+5=25
W=20,
L=25
