Answer:
No ABC is not a triangle
Step-by-step explanation:
Perimeter = 22 cm
AB = 8 cm ; BC = 8 cm
AC = 22 - ( 8 + 8 ) = 6 cm
But all those sides doesn't follow Pythagorean Theorem(AB^2 + BC^2 = AC^2) ....because 8^2 + 8^2 isn't equal to 6^2 ......
Had it followed the theorem , it could have been a right angle triangle...
Answer:
(X+5)(x^2-5x+25)
Step-by-step explanation:
Answer:
If one pair of opposite sides in a four sided figure are both opposite and parallel, then the figure is a parallelogram.
Step-by-step explanation:
You are trying to find the side between the right angle and the degree (This is known as the adjacent)
You are given degree 42
You also given the longest side of 19 (This is known as the hypothenuse)
Cosine: adjacent/hypothenuse
Cos42 = x/19
0.7431448255 = x/19
x = 19 * 0.7431448255
x = 14.11975168, round to tenth
Solution: x = 14.1
Yes because
3 is x
And 5 is why so it’s
5 = 2 x 3 - 1
5= 6 -1
Which is 5
