Answer:
4th is the answer
Step-by-step explanation:
The answer is absolute dictator
Sin2x=2sinxcosx, cos2x=1-2sin^2x
sin(2x)+cos(3x)=2sinxcosx+cos(x+2x)
cos(x+2x)=cosx(1-2sin^2(x))-sinx2sinxcosx
sin(2x)+cos(3x)=2sinxcosx(1-sinx)+cosx(1-2sin^2(x))
The solution to this question is 20.6666666
<u><em>Answer:</em></u>
second leg = 24 units
hypotenuse = 24√2 units
perimeter = 48 + 24√2 units
<u><em>Explanation:</em></u>
<u><em>1- getting the other leg:</em></u>
Since the triangle given is an isosceles triangle, this means that the two legs are equal in lengths.
We are given that one of the legs is 24 units, therefore, the other leg is also 24 units
<u><em>2- getting the hypotenuse:</em></u>
The given triangle is a right-angled triangle. We can use Pythagorean theorem to get the hypotenuse as follows:
(hypotenuse)² = (24)² + (24)²
(hypotenuse)² = 1152
hypotenuse = 24√2 units
<u><em>3- getting the perimeter:</em></u>
The perimeter of the triangle is the summation of its three sides.
In the given triangle, we have:
two legs = 24 units
hypotenuse = 24√2 units
Therefore:
perimeter = 24 + 24 + 24√2
perimeter = 48 + 24√2 units
Hope this helps :)
