we have to apply the pythagorean theorem and we will get that x^2=11^2-7^2
x^=121-49=72
x=sqrt72=8.4
Answer:
6√2
Step-by-step explanation:
this makes a right angled triangle
hypotenuse=11
one adjacent sides=7
by pythagora's theorem=
adjacent side²+adjacent side²=hypotenuse²
∴ ײ+7²=11²
ײ+49=121
ײ=121-49
x²=72
x=√72
x=6√2
