Answer: True
One angle of a right triangle = 90°
Let x = the acute angle of one angle.
Let y = the angle of the other angle.
Because the sum of angles in a triangle is 180°,
x + y + 90 = 180
x + y = 90
y = 90 - x
Therefore the angles for each of the two triangles are
x, 90° - x, 90°.
The two triangles are therefore similar because of AAA (Angle, Angle, Angle).
Answer:
7
Step-by-step explanation:
form a proportion
12/2=42/x
cross multiply
12x=84
x=7
Answer:
Step-by-step explanation:
<u>Given</u>
<u>We see J is between H and K, so </u>
- KH = HJ + JK
- 2x + 5 + 3x - 7 = 18
- 5x - 2 = 18
- 5x = 20
- x = 4
Answer:
J(-5,2), A(-5,4), and N(-1,1)
Step-by-step explanation:
I think it's A.
The difference = x - 5, where x is Jamie's height.
