Answer:
Yes, acute
Step-by-step explanation:
Because 10 and 12 add up to more than 16, it is possible to construct an acute triangle with these side lengths. Since 10^2 + 12^2 ≠ 16^2, we know that any triangle so constructed will not be a right triangle.
= 105.57
= 105.6 cm²
n= -52/7
7(n+8)=4
(7×n)+ (7×8)=4
7n +56=4
7n +56-56=4-56
7n+0= -52
7n=-52
7n/7= -52/7
