Answer:
Step-by-step explanation:
The total number of sums (not distinct) is 
, because we're removing without replacement.
Count the sums that fit the stipulation (sum 
5):
There are 8 sums that work. Therefore, the desired answer is 
Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
x + y = 1 → (1)
2y - x = 8 → (2)
Adding the 2 equations term by term will eliminate the x- term
(x - x) + (y + 2y) = (1 + 8), that is
3y = 9 ( divide both sides by 3 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for y
Substituting y = 3 in (1)
x + 3 = 1 ( subtract 3 from both sides )
x = - 2
Solution is (- 2, 3 )
I think it would be 7.5!!
It’s isosceles because 2 acute angles and one 90 degree angle makes an isosceles triangle
