D. None. Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees. Hope this helps.
Answer:
Step-by-step explanation:
If a, b and c are the lengths of the triangle's sides, then
Since
then
Thus,
Answer:
Marc's age is 12
Step-by-step explanation:
Let
x ----> Marc's age
y ---> Tony's age
z ---> Ben's age
we know that
the sum of their ages is 40
so
-----> equation A
Marc is half as old as Tony
so
----> equation B
Marc is three times as old as Ben
so
----> equation C
substitute equation B and equation C in equation A
solve for x
therefore
Marc's age is 12
From the equation, the slope is 2.
Point slope form: y - y1 = m(x - x1)
y + 1 = 2(x + 1)
Hope This Helped! Good Luck!
