Answer:
If x = 3y and 3y = x, then y = 1/3x.
you simply have to add all of the numbers together, so it'll be 2+5+12+7+1 or 27, therefore the answer is B
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:
4 hours
Step-by-step explanation:
25 pages -> 30 min
5 pages -> 6 min
200 pages -> 6*40 min =240 min
240/60= 4
Thus, the answer is 4 hours
