Answer:
Step-by-step explanation:
We have been given an equation . We are asked to find the solutions of our given equation.
We will use splitting the middle term method to solve quadratic equation.
We will split middle term of our given equation into parts such that whose product is and whose sum is 3.
We know that such two numbers are .
Using zero product property, we will get:
Therefore, the solutions for our given equation are .

Answer:
$60
Step-by-step explanation:
sorry if I'm wrong ^-^
Scalene just means all the angles are different. Not particularly helpful; we'll check at the end.
Obtuse is bigger than 90, so this will be the biggest angle in the triangle, let's call it A. A>90 degrees.
B=56 degrees.
C is the smallest angle. It will be smaller than B, since A is obtuse.
The two equations we can write are
A = 3C
A+B+C=180
3C + 56 + C = 180
4C = 124
C = 31
A = 3(31) = 93
Check:
31 + 93 + 56 = 180, good
all three different, scalene, good
93 is obtuse, good
Answer: Triangle has angles 31°, 56°, 93°
Answer:
-56
