Please answer these 6 problems. Find the missing side to nearest tenth.
Vinil7 [7]
Since these are right triangles you can use the pythagorean theorem
a² + b² = c² 
a = one leg of the triangle
b = the other leg of the triangle
c = the hypotenuse

1. 4² + 3² = c²
   16 + 9 = c²
   25 = c²
  √25 = √c²
    5 = c
    c = 5cm

2. 5² + 12² = c²
    25 + 144 = c²
    169 = c²
    √169 = √c²
     13 = c
      c = 13in

4. 7² + 9² = c²
    49 + 81 = c²
    130 = c²
    √130 = √c²
    11.4 = c
    c = 11.4cm

5. a² + 10² = 15²
    a² + 100 = 225
    a² = 125
    √a² = √125
    a = 11.2ft

Step-by-step explanation:

Perimeter is sum the distance round a figure.

if a shape has those, they signify that the shape has two side that are equal

a)  4 + 4 + 2 + 2 = 12. The top part is equal to the bottom part signified by those two lines. And the left is equal to the right .

b)  10 + 10 + 7 = 27

c) 5 + 5 + 8 + 6 = 24

d)  3 + 3 + 6 + 6 = 18

e) 2.5 + 2.5 + 2.5 + 2.5 = 10

f) 12 + 7 + 7 + 5 + 5 = 36
