Answer/Step-by-step explanation:
a. Unknown side, b, using the Pythagorean theorem is solved as shown below.
Unknown side, b, = 36 km
b. Perimeter of the triangle = sum of all the sides of the ∆ =
c. Area of triangle = ½*base*height
where,
Base = 36 km
Height = 27 km
Answer:
4√2i , -4√2i.
Step-by-step explanation:
3x^2 + 64 = 2x^2/2
3x^2 + 64 = x^2
2x^2 + 64 = 0
2x^2 = -64
x^2 = -32
x = +/- √-32
x = +/- √16* -2
x = +/- 4√2 i.
First the question is sayin that x will be substituted for -10
so for every x put -10
8(-10)=6(-10)-20
then you multiply to get the next expression
so you know that 6 times -10 =-60 and you know that 8 times -10=-80 so now you have
-80=-60-20
now you just solve so you would just subtract -60-20 which would equal -80
so your answer is -80=-80 which is true
The volume becomes 1/3 of the original. With a rectangular base, volume of a pyramid is V=(length*width*height)/3. Cutting the height to 1/3 of the original length will make the total volume 1/3 of the original volume.
