How you find the area of a triangle is base × height ÷ 2. So the equation would be 6×3=18 18÷2=9, so the answer is 9. Hope this helped!
So we can call first number "n"
Then all five integers would be n, n+1, n+2, n+3, n+4
So sum of them would be 5n + 10 = 100
Now you can solve for n:
5n + 10 = 100
5n = 90
n = 18
Verify: 18 + 19 + 20 + 21 + 22 = 100. All good.
So answer is 18
Answer:
acute triangle, obtuse triangle
Step-by-step explanation:
The sums of interior angles of all triangles are 180°, but the triangles are only similar if their corresponding angles are congruent.
An acute triangle and an obtuse triangle both have angle sums of 180°, but can never be similar to one another.
The answer is -3y^2-6y-17
