Why can 2 obtuse angles make a right triangle please help

djverab [1.8K]

They can NOT. A right angle is 90°. An obtuse angle is greater than 90°. All the angles in a triangle must add up to exactly 180°. If two angles are greater than 90° then they will add up to greater than 180, beacuse 90 plus 90 equals 180. You cannot have a triangle with two obtuse angles because they will add up to greater than 180°.

What is the solution to the proportion 3y-8/12=y/5? can someone help me do this?

RideAnS [48]

$\displaystyle\\
 \frac{3y-8}{12} = \frac{y}{5} \\ \\ 
5(3y-8)=12y\\\\
15y-40=12y\\\\
3y = 40\\\\
\boxed{y = \frac{40}{3}}$

Explain how you could use a number line to show that -4+3 and 3+(-4) have the same value.which property of addition states that

Anna007 [38]

For -4+3,
1. start with zero
2. move to left (-x axis) for 4 units (-4)
3. then move to right (+x axis) for 3 units (+3)

For 3+(-4)
1. Start with zero
2. Move the point to right side by 3 units (+3)
3. then move the point to the left by 4 units (-4)

For both you'll stop at -1.
