Answer:
25-15=w;w=10
Step-by-step explanation:
25 is the most it can weigh, and 15 is how much it weighs at the moment. The w stands for how much the weight can go up.
The correct answer is: 330
Explanation:
The formula for combination is given as follows:
--- (1)
Where n = 11
r = 4
Plug in the values in equation (1) and calculate:

Hence the correct answer is 330.
This is the concept of trigonometry, to get the possible length of side a we use the sine rule which states that:
a/sin A=b/sin B=c/sin B
where;
a,b and c are the sides
A,B and C are the angles
thus the value of A could be as follows;
assuming the triangle is an isosceles triangle, the base angles will be:
(180-40)/2=70
thus;
15/sin 70=a/sin 40
a=(15sin40)/sin70
a=10.26 inches
thus the possible size of a=10.26 inches
To solve this, it might be easier to draw it out (see the picture below). I split it into two triangles and used trig functions to find the altitude. I used the big triangle to find theta, and the used theta to find the side of the altitude. *remember that sine= opposite/hypotenuse*
