Answer:
2.4
Step-by-step explanation:
Look up 30-60-90 right triangle and use that formula. Since the angle in the middle is 90 degrees, it should work. The side of x would be double of the given side 1.2... this is what I would do
Answer:
X=-1
Y=-9
Step-by-step explanation:
x^2+2x-8
x^2+2x +1 =8+1
(x+1)-9
Check out the attached image. I drew what I think your book is showing. The figure on the left is triangle ABC without any extended segments. The figure on the right has segment AB extended shown in red. This forms the exterior angle x
The rule that connects x, y and z together is the remote interior angle theorem. It says that adding two interior angles is going to be equal to the exterior angle that is not touching either interior angle. The "remote" part means "far away" so just think of the two angles that are furthest way or not touching the exterior angle in question.
In terms of algebra, the rule is
x+y = z
