Answer:
B= 6
Step-by-step explanation:
pythagorean theorem formula is a² + b² = c²
so: 8² + b² = 10²
then: 64 + b² = 100
subtract 64 from both sides to get b²= 36
square root 36 and you get 6 for b
answer: B= 6
triangle is a good shape... but
Blank=6
6 times 8 =48
because it is like 6 8s ok so 8+8+8+8+8+8=48
or
6+6+6+6+6+6+6+6=48
try it on paper and you will see I am right :)
