Correct
a right triangle will have 1 right angle and 2 acute angles.
an obtuse triangle will have 1 obtuse triangle and 2 acute angles.
Y + 4 + 3(y+2) first distribute the 3
y + 4 + 3y + 6 then add like terms
4y + 10
therefore your answer should be 4y + 10
I believe it’s 9 but unsure sorry
You will take 100 = 15.5x - 7 and solve.
the end product comes out to be 6 = x or (OCD is kicking) x = 6.
hope this helps (; hmu if u need more info
