What type of triangle has no congruent sides and one angle that has a measure greater than 90° but less than 180°? A.) acute scalene triangle
B.) right isosceles triangle
C.) equiangular equilateral triangle
D.) obtuse scalene triangle

D.) obtuse scalene triangle

Step-by-step explanation:

acute triangle: 3 acute angles

right triangle: 1 right angle, 2 acute angles

obtuse triangle: 1 obtuse angle, 2 acute angles

scalene triangle: no congruent sides

isosceles triangle: 2 congruent sides

equilateral triangle: 3 congruent sides

The question is:

"What type of triangle has no congruent sides and one angle that has a measure greater than 90° but less than 180°?"

That means scalene and obtuse.

D.) obtuse scalene triangle

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

i found two solutions,   n = 2 • ± √3 = ± 3.4641
