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°.

Ed is 7 years older then ted Ed's age is also 3/2 times ted's age how old are ed and ted

Rasek [7]

Answer:

if i'm right ted is 14 and ed is 21

Step-by-step explanation:

if ed is 7 years older than ted and is 3/2 times eds age, than we have to find out how much dose 2 represent in the equation 3/2 so we know that ed is seven years older than ted. so that means that if the equation 3/2 was 1/2, 1 would represent 7 years. (i hope your following me) so if 1 represents 7 than 2 must represent 14 and that would be the age of ted because in the equation 3/2 the 2 would represent teds age. and if the 2 represents teds age than 3 would be eds age. so 7 x 3 = 21. (this is my first time answering a question so sorry if i'm confusing)

Hello can you please help me posted picture of question

We have to find the greatest common factor from the given expression. The greatest common factor is such a term which can be taken out common from each term of the expression leaving behind no common element between the terms of the expression.

If you observe the given polynomial, you will see that the greatest common factor is 7x. So the factorization of the polynomial will be:

$7 x^{5} +49 x^{2} +28x \\ \\ 
=7x( x^{4} +7x+4)$

So option A gives the correct answer to the question
