Answer:
No
Step-by-step explanation:
As you probably know, triangles have 3 sides. The longest side is called the hypotenuse. In this case, the hypotenuse is 10.3. Now, you might or might not know the pythagorean theorem, which states that the <em>a² + b² =c ². </em>
In this case, we can say that 4.4 is <em>a </em>and 8.3 is <em>b. </em>Now if we square 4.4 and add it to 8.3 squared, we get 88.25. However, if you square 10.3, you get 106.09. Thus, the values cannot be this way. So, your answer is no.
To find the hypotenuse of the triangle
you use the length of the legs
Plug it into the Pythagorean Theorem
so


is one of the legs
and

is the other leg
then

is the hypothenuse
In step 3, Mark forgot to multiply 5 · 5, so he ended up with 5 in the denominator instead of 5 · 5 = 25
An "obtuse" angle is an angle that's bigger than 90 degrees.
So two obtuse angles would add up to more than 180 degrees.
But the three angles inside a triangle always add up to exactly 180 degrees.
So two of them can't be obtuse.
