To be honest in my opinion, without offending anyone or being condescending, and without triggering anyone, I just want to say I got nothing to say but I have none
Answer:
9.19
Step-by-step explanation:
Using Law of sines to find other two lengths:
a/sinA=b/sinB
let a be length of side unknown and b be hypotenuse then sinB=sin90 and sinA=sin45
a/sin45=13/sin90
a=13sin45
a=13(0.707)
=9.19
As the given triangle is isosceles hence the length of other two legs will be same i.e 9.19 !
Short answer: 100
I assume you want to find x.
We want an equation that says that x is equal to 105cm, minus that 5 percent, because that is his height before the 5% was added. That looks like:
x + 0.05x = 105
(0.05 is 5% in decimal form, which is necessary in equations like this).
x + 0.05x = 1.05x
1.05x = 105.
Isolate x by dividing both sides by 1.05
1.05x / 1.05 = x, 105 / 1.05 = 100
x = 100, so he was 100cm tall before summer
My original answer was 99.75. This is wrong because I used the 5% of 105, which is wrong because in the question it says his original height (which is x) had 5% added to it. So its 5% of x, not 5% of 105. This changes the whole equation.

Answer:
tan M = 
Step-by-step explanation:
To obtain tan M we require to find KL
Using Pythagoras' identity in the right triangle.
KL² + LM² = KM²
KL² + 7² = 25²
KL² + 49 = 625 ( subtract 49 from both sides )
KL² = 576 ( take square root of both sides )
KL = 
= 24
Then
tan M = 
= 
=
