Start by mult. both 0.4 and 5.12 by 100. What is 40 divided by 512?
___.078_______________
512 / 40.000
3584
-----------
4160
4096
---------
64 and so on. Calculator answer is 0.078125.
<span>Let’s say we have a starting point (0,0), the point (4,3) are distance apart at 90 degrees, hence the hypotenuse to those two distance will be 5.
Therefore sin q = 4/5.</span>
Answer:
they are complementary
Step-by-step explanation:
So it is an isosceles triangle that means that the bottom two angles are equal...
so
40 = 5x
divide both sides by 5 and you get 8
now the triangle angles add up to 180
we make an equation out of it...
(2y + 20 ) + ( 5(8)) + 40 = 180
2y + 20 + 40 + 40 = 180
combine like terms
2y + 100 = 180
so subtract 100 from both sides
2y = 80
divide by 2 to isolate the variable
y = 40
You are correct!!! :)
You multiply by 10 or more
