So you want to find the opposite side
we could use SOH-CAH-TOA
We want the opposite side and we have the Hypotenuse
so we use Sin (angle) =opp/hyp
sin(35) = x/15m
x= 15m * (sin 35)
can you do that in you calculator? make sure to be in degrees
hope that helps
if you need more help just ask
Answer:
∠ QRS = 43°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4n - 9 + 5n - 18 + 90 = 180, that is
9n + 63 = 180 ( subtract 63 from both sides )
9n = 117 ( divide both sides by 9 )
n = 13
Thus
∠ QRS = 4n - 9 = 4(13) - 9 = 52 - 9 = 43°
∠ RSQ = 4n - 18 = 4(13) - 18 = 65 - 18 = 47°
L*w=A
l*9=3
(l*9)/9=3/9
l=1/3 of a meter.
Answer:
m= -9
Step-by-step explanation:
17 + m = 8
subtract 17 from both sides
(17-17) + m = 8-17 = -9
m= -9 check answer by replacing m with -9
17 + (-9)= 8
Answer:
Step-by-step explanation:
1 billion = 10^9
10^9 people * (10 Liters)/person = 10^10 Liters
