Me #1-6 i will make your answer the brainlest of all

1. x=91 obtuse
2. x=75 acute
3. x=90 right
4. x=94 obtuse
5. x=48 isosceles 
6. x=60 equilateral

The trick to finding an angle in a triangle when given the other 2 angle values is to know that all three angles add up to 180. so:
angle1 + angle2 + angle3 = 180

so for problem #1
x + 45 + 44 = 180

this can be written:
x = 180 - 45 - 44
x = 91

so answer is 91
you can use this to easily find other angles on your own.

to classify:
scalene = no angles are equal
right = 1 angle is 90
isosceles = 2 angles equal
equilateral = all angles equal

using this you can now classify on your own
