The triangles are congruent by SAS, so the two angles with 7x and 3x+16 are equal. So
7x=3x+16
4x=16
x=4
So KJL=7(4)=28.
Answer:
positive
Step-by-step explanation:
The discriminant is positive
If there are 2 real roots ( where it crosses the x axis), then the discriminant is positive
Answer:
The answer is they are congruent.
Step-by-step explanation:
They have two congruent sides and share one side, so they are congruent by SSS.
I hope this helps! :)
Answer:
look down
Step-by-step explanation:
we need to find 10% and multiply it by 4 to get 40 percent
10 percent of 2200 is 220 because 2200 divided by 10 is 220 then we multiply this by 4 and we should get 880
Answer:
A) 0.9(sin50)
Step-by-step explanation:
Since this is a right triangle, we can use
sin a = opposite side/ hypotenuse
sin 50 = x /.9
Multiply each side by .9
.9 * sin 50 = x/.9 * .9
.9 (sin 50) = x
