Answer:
Find the two ways to find the difference of : 
First way:
To convert this fraction into decimal.
We have to make the denominator 100.
i.,e
now,
Second way:
Convert to 
and 4.93 to 
,
Now:
If the legs of a right triangle are a and b and the hypotnuse is c then
a²+b²=c²
so we are given
the legs are x and √7
and the hypotnuse is √19
so
x²+(√7)²=(√19)²
x²+7=19
minus 7 both sides
x²=12
sqrt both sides
x=√12
x=√(4*3)
x=(√4)(√3)
x=2√3
Answer:
C. Scalene triangle
Step-by-step explanation:
What I would do is add all of the angles to 180 and then solve for x.
6x + 10 + 7x + 15x + 2 = 180
28x + 12 = 180
28x = 168
x = 6
Then, plug in 6 for each expression to find each angle
6(6) + 10 = 46
7(6) = 42
15(6) + 2 = 92
Since none of the angles are equal and one of the angles is over 90 degrees, triangle GFH is a scalene triangle
