Soh cah toa is your best friend in trig
sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent
X is opposite from 43 degrees.
16 is the hypotenuse because it’s the longest side.
We need to use sin(x) because we’re given the opposite/hypotenuse ratio.
For sin(x) plug in the angle for x:
sin(43) = X/16
Multiply both sides by 16.
X = 16*sin(43)
You can plug it into your calculator.
Answer:
(A)
(B)
Step-by-step explanation:
(A)
we are given
Firstly, we will find few terms
so, we will get terms as
5, 7 , 9 , 11
we can see that this is arithematic sequence
First term =5
common difference =d=7-5=2
now, we can use nth term formula
now, we can plug values
(B)
we can plug n=10
Answer:
the first one is the expression
The only factors of 73 are itself and one so it is a prime number.
