Answer:
using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2
a²+b²=c²
(9/10)²+(11/5)²=(11/2)²
81/100+121/25=121/4
lcm of 25 and 100 =100
(81+484)/100=121/4
565/100=121/4
113/20=121/4
since they are not equal therefore it's not a right angle triangle
7/10
Step-by-step explanation:
2/5 turns into 4/10
4/10 plus 3/10 is 7/10

-1/8
(-2)^-3
The negative exponent means it's the inverse.
1 / ((-2)^3)
-2 cubed is -8.
1 / (-8)
So the simplified answer is -1/8.
