Answer:
Step-by-step explanation:
we know that
The measure of the interior angle in an equilateral triangle is equal to 60 degrees
The measure of the interior angle in a regular octagon is equal to
where
n is the number of sides
In this problem we have
substitute
we have that, based in the diagram
The sum of the interior angle of the equilateral triangle plus the interior angle of a regular octagon plus the value of x must be equal to 360 degrees (complete circle)
so
solve for x
Answer:
It's B because If you cover the blue you will see space that looks like a triangle. Do the same to A. You see how in B the Triangle looking thing is lower than A because A triangle thing is like more up and wider so it has space. Also B has a little space than A
Step-by-step explanation:
The radius is the cube root of 750. THe surface area is 3000 pi centimeter square.
Let your age = X
Now you have 500 - 3x = 278
Subtract 500 from each side:
-3x = -222
Divide both sides by -3:
x = -222 / -3
x = 74
You are 74 years old.
Answer:
-7 .5+ 2.5 i
Step-by-step explanation:
(-11+i) (-4+ 4i)
find the midpoint
use the same formula for midpoint we use for x and y
midpoint = (a1+a2)/2 +(b1+b2)/2 i
midpoint =( -11+-4)/2 + (1+4)/2 *i
= -15/2 + 5/2 i
-7 .5+ 2.5 i
