(2x-5y)+(x+y)=(2x+x)+(-5y+y)=3x-4y.
therefore:
(2x-5y)+(x+y)=3x-4y

=======================================
Explanation:
Recall that tangent is the ratio of opposite over adjacent
tan(angle) = opposite/adjacent
So for reference angle G, we say,
tan(G) = JH/GJ = 2/1 = 2
We'll treat tan(H) in a similar fashion, but the opposite and adjacent sides swap roles. That means we'll apply the reciprocal to the result above to get 1/2 for tan(H)
-----------
So we have this interesting property where
tan(G)*tan(H) = 2*(1/2) = 1
In general,
tan(A)*tan(B) = 1 if and only if A+B = 90 degrees
-----------
Side note: The side sqrt(5) isn't used at all.
Answer:
164.48 or 164.5
Step-by-step explanation:
So, to make it simpler, you can do the circle like this: 3.14×(8×8). Then you can work down!
3.14 × 64
200.96
and then because it's halved, you divide by 2
100.48
then that's the half circle
The square would just be 8×8=64
then add the circle and the square and viola!
164.48
Yeah it's true, a point has no width, hight, or depth
