can some please help me with this i have multiple things i need to do for my other classes and this is my hardest one pls help me im begging you my 1st term will be ending in a week and my grades are really not it, so if you could help me i would really appreciate it!

You can use Pythagorean Theroum, its not that hard. Use the formule a^2+b^2=c^2

The a is one side, the b is also another side but the C is the hypot use. The hypotunes (the largest side of a triangle) is usually the diagonal of the triangle like the one thats the longest.

(I’m gonna do a few)

1) 10^2+7^2=c^2

100+49=c^2

149=c^2

square root of 149 is about 12.21

(Skipped to 3 because of different example)

3) We know the hypotenuse but we don’t know B

so

16^2+b^2=27^2

256+b^2=729

b^2=473

About 21.75

6) Well this is a trapezoid and we want to find the side

So the two triangle’s sides are 17 and 19

We know 17 and 19 becuase the 17 was stated and the 19 was equal on both sides

use pythagoream theorem

17^2+b^2=19^2

289+b^2=361

B^2=72

8.49

Now thats the triangle’s sides

Now we double it becuase there are 2 of them

8.49(2)=16.98

Now we subtract that from 31

31-16.98=14.02

x=14.02

(I’d do more but I have no more space)
