OK, let's try with no figure. We have an isosceles triangle sides s,s, and b.
Opposite b is angle t.
Draw the altitude h to bisect t. We have two right triangles, legs b/2 and h, hypotenuse s. The angle opposite b/2 is t/2 so
sin(t/2) = (b/2)/s = b/2s
So we arrived at the first part,
b = 2s sin(t/2)
The area of a triangle with sides s,s and included angle t is
A = (1/2) s² sin t
Answer:
The first, third, and fourth answers are correct!
In the given question all the information's are provided based on which the answer to the question can be easily deduced. It is already given that the population of the world in the year 2002 was estimated to about 6 billion. Among them 20% of the people lived on an an income of less that $1 per day.Firstly let us convert 6 billion from words to numbers.
6 billion = 6000000000
Now
Number of people earning less that $1 per day = (20/100) * 6000000000
= 6000000000/5
= 1200000000
So the number of people earning less than $1 per day is 1200000000
Answer:
B is correct
Step-by-step explanation:
No, it is not equivalent to (x5)3. If yoh were to put 1 as a substitute for x5; 1 × 1× 1 equals 1, as represented in x5x5x5. The thing is (1)3 equals 3, as shown in (x5)3. You can substitute x5 for any number. x5x5x5 is more like it is raised to the third power than multiplied by 3.
Hope this helps!!!
