This triangle is a scalene triangle because all three of the side lengths aren't equal.All of the three angles have different measures.This triangle would have been classified as acute because the angles are less than 90 degrees.If all angles were 90 degrees then it would be right and if they were more than 90 it would have been an obtuse triangle.Hope this helped!!!!!!!!

Answer:

Option D

Step-by-step explanation:

In the first three options we can evaluate the values of x with the help of Sine Rule for all the triangles

The Rule says

$\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}$

Where a , b and c are the sides opposite to the angles A, B and C of any ΔABC.

Hence , in order to determine unknown values of sides or angles , we need any 3 values from all 3 sides and 3 angles in a triangle. First Three options give us three values but the last option gives only 2.

Example

in first option we can apply Sine Rule as

$\frac{\sin 84}{x}=\frac{\sin 63}{3}$

$\frac{0.994}{x}=\frac{0.891}{3}$

$x=\frac{0.991 \times 3}{0.891}$

$x=\frac{2.973}{0.891}$

$x=3.336$

FINAL DUE IN 30 MINUTES: the equation 2y + x = 0 is shown on the graph below as a

julia-pushkina [17]

Answer:

Red line

Step-by-step explanation:

2y+x=0

2y=-x

y=-x/2

Put the equation into y=mx+b so you would need to subtract the x to put it on the right side so then you’ll have 2y=-x+0 then divide by 2 to get the y by itself then you’ll have y=-2x+0 that means the line would be negative and the y-intercept is 0 and the only line that follows that is the red line.

Can three segments with length 4 cm, 6cm, and 11 cm be assembled to form an acute triangle, a right triangle, or an obtuse trian

adoni [48]

Answer:

Step-by-step explanation:

According to the Inequality Theorem, the sum of 2 side of a triangle must always be longer than the third one. 4 + 6 = 10 which is not larger than 11.
