Check the picture below.
now, notice, for the angle hAC, the hypotenuse is hA, and the adjacent side is CA, therefore,
make sure your calculator is in Degree mode, if you need the angle in degrees.
Answer:
B seems right
Step-by-step explanation:
Step-by-step explanation:
<h2>1).</h2>
The sum of interior angles of a polygon is given by
<h3>( n - 2) × 180°</h3>
where
n is the number of sides
From the question, the number of sides is 50 that's n = 50 .
Substitute the value into the above formula and solve.
We have
(50 - 2 ) × 180 = 48 × 180
<h3>The answer is 8640°</h3>
<h2>2).</h2>
The sum of interior angles of a polygon is given by
<h3>( n - 2) × 180°</h3>
where
n is the number of sides
From the question the sum of the angles is 2160°
Substitute the values into the above formula and solve for the number of sides.
That's
2160 = (n - 2) × 180
2160 = 180n - 360
180n = 2160 + 360
180n = 2520
Divide both sides by 180
n = 14
<h3>Therefore the number of sides is 14</h3>
<h2>3).</h2>
The exterior angle of a polygon can be found by using the formula
<h3>
</h3>
where
n is the number of sides
From the question the number of sides is 6 that's n = 6.
Substitute the value into the above formula and solve.
We have
<h3>
</h3>
We have the final answer as
<h2>60°</h2>
Hope this helps you.
Answer:
The numbers are x = 3 and y = 1. Therefore the value of xy is 3.
Step-by-step explanation:
In order to calculate the numbers we will simplify the equation, this is done bellow:
2*x + x(2^2) + (y*2^3) + (y*2^4) = 42
2*x + 4*x + 8*y + 16*y = 42
6*x + 24*y = 42
We can divide the whole equation by 6, so we have:
x + 4*y = 7
The only possible combination of numbers that are positive and integers that will make the equation valid is x = 3 and y = 1. Therefore he value of xy is 3.
