The answer is b, I’m not saying it’s true but just predicting xoxoox
The answer is 90 degrees. SO it would be B
Is there like a question???
Answer:
28
Step-by-step explanation:
Use the pythagorean theorem and solve for a:
a² + b² = c²
a² + 21² = 35²
a² + 441 = 1225
a² = 784
a = 28
So, the missing length is 28.
