F(x)=x (and then plus something, i’m not sure)
Answer:
6.04%
Step-by-step explanation:
First, find the difference, 19.3 - 18.2 = 1.1
Find the percentage of 182 is 11. 11/182 = about 0.0604
Percent = Decimal * 100
0.0604 * 100 = 6.04
Hope this helps :)
Answer:
N = 18
Step-by-step explanation:
The triangles are similar, thus the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
5N = 90 ( divide both sides by 5 )
N = 18
Answer:
60°
Step-by-step explanation:
We'll begin by calculating EC. This can be obtained as follow:
Angle EAC = 39°
Hypothenus = EA = 3.7 m
Opposite = EC =?
Sine EAC = Opposite /Hypothenus
Sine 39 = EC / 3.7
Cross multiply
EC = 3.7 × Sine 39
EC = 2.3 m
Finally, we shall determine angle BEC. This can be obtained as follow:
Adjacent = EC = 2.3 m
Hypothenus = BC = 4.6 m
Angle BEC =?
Cos BEC = Adjacent / Hypothenus
Cos BEC = 2.3 / 4.6
Cos BEC = 0.5
Take the inverse of Cos
BEC = Cos¯¹ 0.5
BEC = 60°
Thus, angle BEC is 60°
