Answer:
the answer would be x=3
Step-by-step explanation:
the lines the have 1 line across it equal the same. same for the ones with 2. for example AB has one line across so it also equals CD because it has one line across (in the little octagonal shape). BC has two lines and so does AH so BC=AH
The answer is no. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third.
Answer:
value of 4 tan 45° +(2 sin 45°) (6 cos 45°) is 10.
Step-by-step explanation:
To solve this question we need to know value of
tan 45° = 1
sin 45° = ![1/\sqrt{2}](https://tex.z-dn.net/?f=1%2F%5Csqrt%7B2%7D)
cos 45° = ![1/\sqrt{2}](https://tex.z-dn.net/?f=1%2F%5Csqrt%7B2%7D)
we will be using above value sin the given expression as shown
![4 tan 45 +(2 sin 45) (6 cos 45) = 4*1 + (2*1/\sqrt{2} )(6*1/\sqrt{2})\\ = 4 + (2/\sqrt{2}) (6/\sqrt{2})\\= 4 + (2*6)/(\sqrt{2}*\sqrt{2})\\= 4 + (12/2)\\= 4 + 6 = 10](https://tex.z-dn.net/?f=4%20tan%2045%20%2B%282%20sin%2045%29%20%20%286%20cos%2045%29%E2%80%8B%20%3D%204%2A1%20%2B%20%282%2A1%2F%5Csqrt%7B2%7D%20%29%286%2A1%2F%5Csqrt%7B2%7D%29%5C%5C%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%3D%204%20%2B%20%282%2F%5Csqrt%7B2%7D%29%20%286%2F%5Csqrt%7B2%7D%29%5C%5C%3D%204%20%2B%20%282%2A6%29%2F%28%5Csqrt%7B2%7D%2A%5Csqrt%7B2%7D%29%5C%5C%3D%204%20%2B%20%2812%2F2%29%5C%5C%3D%204%20%2B%206%20%3D%2010)
Thus, value of 4 tan 45° +(2 sin 45°) (6 cos 45°) is 10.

We are asked to prove tan(θ / 2) = sin θ / (1 + cos θ). In this case, tan θ is equal to sin θ / cos θ. we can apply this to the equality. sin θ is equal to square root of (1-cos θ)/2 while cos θ is equal to <span>square root of (1 + cos θ)/2.
Hence, when we replace cos </span><span>θ with </span>square root of (1-cos θ)/2, we can prove already.
