Answer:
1. 10
2. 12
3. Sqrt 130
4. Sqrt 45
Step-by-step explanation:
To find the missing side of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem is
where a and b are the legs with a being the smallest and c is the hypotenuse.
1. a=6, b=8, c=?

2. a=5, b=?, c=13

3. a=7, b=9, c=?

4. a=2, b=?, c=7

Answer:
105 cm²
Step-by-step explanation:
We can see that the area at the square at the bottom, since one side is 5, is 5²=25. Then, we know that the height of the triangles is 8, the base is 5, and there are 4 of them, so ((5*8)/2)*4=80. Add these up to get 105 as our total
