This requires the pythagorean theorem :
a^2 + b^2 = c^2...where a and b are the legs and c is the hypotenuse..and by the way, this can only be used on right triangles
a^2 + b^2 = c^2
6^2 + 7^2 = c^2
36 + 49 = c^2
85 = c^2...take the sqrt of both sides, eliminating the ^2
sqrt 85 = c
9.22 = c....so the hypotenuse is approximately 9.22 units (thats rounded)
Answer:
-1 this equation is in slope intercept for y=mx+b. the slope is variable m, which in this case is -1. the one is always invisible in front of variable
The first answer would be 2,500,000. You multiply 2,500 by a thousand because 1,000 grams is equal to 1 kg
I am assuming from What I have found is that a is the base , b is angle between a and x and x is the hypotenuse .
So we know that
cos θ =base/hypotenuse
here θ = 3π/8 =67.5 degree
cos 67.5 =0.38268
so
0.38268=a/x
x=25/0.38268
x=65.32873
Answer: X would equal 7 so X=7
