Answer:
Acute Triangle
Step-by-step explanation:
<u><em>Angles in a triangle add up to 180 degrees.</em></u>
So,
x+2x+2x = 180
=> 5x = 180
Dividing both sides by 5
=> x = 36
<u><em>So, The lengths are:</em></u>
=> 36
=> 72
=> 72
<em><u>Since all the angles are less than 90 degrees, It is an acute triangle.</u></em>
At= -5(1/2)
at= -2.5
v= u + at
v= 2 + (-2.5)
v= -0.5
Answer:
8
Dont mind me if i am wrong!
The angle bisector, median, and altitude are all the same things in an isosceles triangle.
That means that the legs of the smaller triangles created by the altitude are 4 root 2.
By special properties of an right triangle, the hypotenuse is 8.
Since the legs of the original right triangle are congruent, the area of the original triangle is 8*8/2.
Now we just simplify:
8*8/2=64/2=32
1) find slope. when its perpendicular, It will be a negative reciprocal to the given slope so m1= -1/m1
m=-1
2)
y =-1x+b
(-3)=-1(2)+b
-3=-2+b
b=-1
3) y=-1x-1
hope I helped!
