Answer:
The correct answer is -9.73°.
Step-by-step explanation:
The procedure is:
sin(x + 34)°=cos(2x+20)°
⇒ tan
= 1 ; [assuming cos (2x+20)° 
0]
⇒ x + 34 = 45 × ( 2x +20)
⇒ x + 34 = 90x + 900
⇒ 89x = -866
⇒ x = -9.73
and also 2x + 20 = 90° ⇒ x = 35°; but this does not satisfy the given equation.
Therefore the value of x is given by -9.73°.
Answer:
The geometric mean of 14 and 20 is 16.73.
Step-by-step explanation:
It is required to find the geometric mean of 14 and 20. Let the numbers are :
a = 14 and b = 20
The geometric mean for two numbers is given by :
Plugging the values in above formula as follows :
So, the geometric mean of 14 and 20 is 16.73.
Answer:
No
Step-by-step explanation:
A triangle can NOT have those lengths because any side of a triangle has to have a length greater than the sum of the other two sides. In this case, 14.4, one of the sides, is not greater than the sum of the other two sides (which is also 14.4).
Hope this helps :)
<h3>
Answer: 40 novels</h3>
================================================
Work Shown:
n = number of novels
(32 ebooks)/(n novels) = 4/5
32/n = 4/5
32*5 = n*4 ............ cross multiply
160 = 4n
4n = 160
n = 160/4 .............. dividing both sides by 4
n = 40
There are 40 novels.
Step-by-step explanation:
2x + 5 (y-1)
16+20
=36
