Answer:
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.
(Iām 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 donāt 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 triangleās 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 triangleās 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
(Iād do more but I have no more space)
