Answer: _
7/45 or 0.15
Step-by-step explanation:
I just did it
The short answer is trial and error. The side lengths "3" and "4" can both be substituted for a² and b² but not c² because their value squared is not high enough since 5² is 25. "c²" as to match the longest side because the smaller numbers will cause the equation to not be true. See Below.
a² + b² = c²
3² + 4² = 5²
9 + 16 = 25
25 = 25
______________________________
a² + b² = c²
4² + 3² = 5²
16 + 9 = 25
25 = 25
______________________________
a² + b² = c²
5² + 4² = 3²
25 + 16 = 9
41 ≠ 9
______________________________
a² + b² = c²
3² + 5² = 4²
9 + 25 = 16
34 ≠ 16
Hope this helped!
Answer:
120 degrees so answer b
Step-by-step explanation:
the opposite angles in the shape are equal so <klm = <kjm. this means the answer is the same as the sum of the other sides so 78 + 42 which is 120 degrees
