Question

Help please

What is the length of GA ?

Answer 1

You know trigonometric ratios ?

Answer 2

NO Can you please explain to me

Answer 3

There are some fixed ratios of the sides of any right triangle.

Answer 4

Here, in this question.. The Ratio of the perpendicular and base is called tangent of angle 45 (given here)
=> 64/AB = tan45
tan 45 has a value 1.. ( You will need to learn trigonometry :P)
so AB has a value of 64 units

Answer 5

Now GA = GB - AB
We have GB = 137
and AB = 64
so subtract and Cheers! :)

Answer 6

73

Answer 7

is that the answer ^^^^

Answer 8

Length of AG is 73 only.
That will be length of "EG"
Consider the bigger triangle..
Similarly tan60 = EG / GA
tan 60 has value sqrt(3)
So, EG has a value 73 sqrt(3) which you have written above.
