Classify the following triangle. check all that apply.60"30a. scaleneb. isoscelesc, equilaterald, righte. obtusef. acute

Step-by-step explanation:

The given triangle as internal angles 90° , 60° and 30°.

Remember that right triangles are defined by having one right internal angle, that is, an angle equal to 90°, which is the case here.

Therefore, this triangle can be classified as a right triangle.

Additionally, notice that its side are all different, 4.2, 7.3 and 8.4, that charactersitcs allow us to give another classification, this triangle is scalene, because it has all sides different.

Therefore, the right answers are A and D.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
