Answer: 12.65 cm
Step-by-step explanation:
Use the Pythagoras theorem,
a^2 + b^2= c^2
You are given the hypotenuse , which is c and another leg which is either a or b, does not particularly matter- rearrange to find the missing length
c^2 - b^2 = a^2
14^2 - 6^2 = 160
Square root 160 to find the missing length
12.65
Hope this helped :)
I think its (<span><span>x^2)</span>+<span>5x</span></span>+<span>49</span>
6x + 7y = 59...multiply by -4
4x + 5y = 41...multiply by 6
