Answer:
Step-by-step explanation:
Using Pythagoras theorem,
AC^2 = AB^2 + BC^2
AC^2 = 4^2 + 15^2
AC^2 = 16 + 225
AC^2 = 241
AC = √241
Answer:
- Sparkle: 104
- Southern: 208
- Scenic: 416
Step-by-step explanation:
The ratios of people at each rink were ...
Sparkle : Southern : Scenic = 1 : 2 : 4
The total number of ratio units is 1+2+4 = 7, so each one must stand for 728/7 = 104 skaters. Then the ratios of the numbers of skaters were ...
Sparkle : Southern : Scenic = 104 : 208 : 416 . . . multiply ratio units by 104
People skating were ...
- Sparkle: 104
- Southern: 208
- Scenic: 416
CP of pen = ₹20
Profit % = 20%
Profit % = profit × 100 / CP
20 = profit × 100 / 20
20 × 20 / 100 = profit
Profit = ₹4
Profit = SP - CP
4 = SP - 20
SP = ₹24
Let new CP be ₹x
Profit % = 25%
SP = ₹24
Profit % = SP - CP
25x / 100 = 24 - x
24x / 100 + x = 24
125x / 100 = 24
5x / 4 = 24
x = 24 × 4 / 5
x = ₹ 19.20

I don't like this computer aided instruction holding my hand. I'll ignore that at first so I can compare my solution to the one being taught.
We can see how a tan factors out; let's see what's left.
We need to factor out a sin x + cos x in the denominator so let's change one of the squared cosines to squared sine.
OK, now I can look at what they did.
First step ok, the box is 2 cos^2 x
Second step they changed the 1, box same as before: 2 cos^2 x
Third box matches our proof, cos^2 x
Fourth box our last box didn't change: cos^2 x
Fifth box: sin x + cos x
