2.59 that’s the correct answer
Answer:
22.84, 5.83
Step-by-step explanation:
Pythagoras theorem states that: a^2+b^2=c^2
So, for red triangle, it will be: 9^2+21^2=b^2
81+441=b^2
522=b^2
square root of 522=b
22.84=b
For purple one,
3^2+5^2=a^2
9+25=a^2
34=a^2
square root of 34=a
5.83=a
I think it’s b.5. Hope this helps. :)
51/4 is the correct answer
its (a) because (a) is C(x)=3x4+30x and 9+21 is 30 so its 3x2+30
