Answer:
96 cm²
Step-by-step explanation:
The lateral surface area (A) is the sum of the areas of the 4 slant faces.
The faces are triangular with area 
bh , thus
A = 4 × × 8 × 6 = 2 × 48 = 96 cm²
Answer: b=13.75
Step-by-step explanation:
Use Pythagorean theorem
a^2+b^2=c^2
We know c, the hypotenuse, because the hypotenuse is opposite the right angle. It is 17
We also know a, one of the legs. It is 10.
Plug the number we know into the formula
10^2+b^2=17^2
100+b*2=289
Subtract the 100 on both sides
b^2=189
Take the square root of both sides
b=13.7477271
Rounded to the nearest Hundredth,
b=13.75
Hope this helped! :)
