Answer:
Domain: {-1,-2,-3,-4}
Range: {4,5}
Step-by-step explanation:
As the range has repeated numbers, you don't have to repeat them.
You just have to go 7x28=[7x20]+[7x8]=196
Yes you could because the obtuse angle is greater than 90 degrees so if the acute angle is inside the obtuse you could get an right angle or an 90 degree angle
I might not understand this correctly because of the misspellings, but if you draw a right angle. There is only 1 right angle... in a right angle.
