For your first question it will be acute and scalene. Because you have a degree that is smaller than 50 degrees and the triangle sides are all deferent sizes and that for they are scalene. For your second question it will be 71 degrees. Because a triangle always has 180 degrees and if you have 38 degrees and 71 just add them and you would get 109 degrees and then you would subtract 180 - 109 an get 71 degrees! Hope that helped! :)
