Triangle has 180 degrees
1 side=180
Then 180-150= 30 degrees
30/2 (for the other two sides)= 15
So, 150 degrees, 15 degrees and 15 degrees.
So it’s probably an isosceles triangle as the two bottom angles are the same number of degrees
Hope this helps :)
The best estimate of the lateral area of the cube with edges that are 2.1 inches long is 4.2
<span>7(6x-4)+2x
=42x - 28 + 2x
= 44x - 28</span>
Sin(theeta) = square root(3)/2
theeta = sin inverse [square root (3)/2]
theeta = 60 degrees
as seen from trignometric table
