The area of the triangles should be 7.5sq. The only question I can answer
Answer:
43
Step-by-step explanation:
2 significant figures means we keep the first 2 and round the 1 place
42.598 we round to 43 since next to the 2 is a 5 so we round up
And 43 are 2 significant figures since none of them are zero
Hopes this helps please mark brainliest
33 would be the answer because it is increaseing, 2,4,6,8,10
Answer:
Step-by-step explanation:
y – 4 = –1 (x – 2)
y – 7 = –1 (x – (–1))
y = –x + 6

Answer:
Triangle ABC is not a Right Triangle
Step-by-step explanation:
The perimeter of a triangle is all of the sides added together so we can model our equation like so:
AB + BC + CA = P
or
8 + 5 + CA = 22
We first combine like terms
13 + CA = 22
Then make the variable have no numbers on its side
13 + CA = 22
-13 -13
CA = 9
So now that we know what CA is, we can determine whether or not its a right triangle
We can use the Pythagorean Theorem for this:
a^2 + b^2 = c^2 (the '^' symbol means 'to the power of')
or
5^2 + 8^2 = 9^2
Now we Solve
5^2 = 25
8^2 = 64
9^2 = 81
25 + 64 =? 81
89 does not equal 81
So Triangle ABC is not a Right Triangle
