Answer:
7.5 cm
Step-by-step explanation:
it is a right triangle, b=10, hypotenuse c=12.5
a^2+b^=c^2 the Pythagorean theorm
a^=c^2-b^2
a^2= 12.5^2-10^2
= 56.25
a=√56.25=7.5 cm
(96+92+80+91+86+x)= 90
________________
6
(445+x)=90
_____
6

445+×=540
-445. -445
x= 95
they need a 95 percent to have an average of a 90%.
