The angles of the triangle are 39°, 51°, and 90°.
Step-by-step explanation:
Step 1:
The sum of all the angles in any triangle is equal to 180°.
We have two of the three angles in terms of x while the third angle is not given directly. Since it is a right-angled triangle, one of the angles equals 90°.
So the angles of the triangle are
and
Step 2:
Now, we substitute all the angles to a sum of 180 to determine the value of x.
So x = 13°. The angles are
The angles of the triangle are 39°, 51°, and 90°.
5 billion * ( 1 + 0.013 ) ^x = 10 billion
1.013 ^x = 10 : 5 = 2
x = 54
1986 + 54 = 2040
In the year 2040 the world`s population will be 10 billion.
1.013 ^x = 10 : 5 = 2
