Please please help me out

Mathematics
1 answer:
Darya [45]4 years ago
8 0

Answer:

\frac{15}{17}

Step-by-step explanation:

Using the Pythagorean identity

sin²x + cos²x = 1, then

sin²x = 1 - cos²x

sinx = \sqrt{1-cos^2x}

Hence

sinΘ = \sqrt{1-(8/17)^2}

        = \sqrt{1-\frac{64}{289} }

        = \sqrt{\frac{225}{289} } = \frac{15}{17}

If G is the circumcenter of triangle ABC, find CG and FB. Round to the nearest tenth if necessary.
Stolb23 [73]

9514 1404 393

Answer:

  CG = 19

  FB = 14.7

Step-by-step explanation:

The circumcenter is equidistant from the triangle vertices, so GA = GB = GC.

The length of GA is given, so we have ...

  GA = 19 = CG

__

Then the Pythagorean theorem can be used to find FB.

  FB² +FG² = GB²

  FB² = GB² -FG² = 19² -12² = 217

  FB = √217 ≈ 14.7

I really need help with this​
Marrrta [24]

Answer:

G=21, F=9, M=6, L=7, E=20, D=15, B=10, R=12.5, T=16, N=13.5, W=18, H=36, Z=12

*I=5*

Step-by-step explanation:

I basically just found the scale factor/proportion from two given sides and then used that to find the remaining sides.

*I'm not sure about 'I' since the edge of the paper was cut off so I want sure if it was a 5 or a 15 on the left most problem in the third row. I assumed it was 15. If it's not, just shout it out in the comments and I'll fix it! :)*

You can fill the letters in at the bottom XD

I hope this helped! :D
