What composite transformations could be used to have triangle 1 turn into triangle 2?
1 answer:
Answer:
see below
Step-by-step explanation:
The vertex order has been reversed, so a reflection is involved. The direction of the short side has been changed by 90°, so a rotation is potentially involved. Depending on the precise rotation and/or reflections, translation may be involved.
One potential set of transformations is ...
- rotate 90° CW about the origin
- translate left 1 and down 3
- reflect across the y-axis
Another potential set of transformations (shown below) is ...
- reflect across the line x+y=1
- translate down 4

Answer:
Th correct option is D. 13
Therefore the value of x is 13.
Step-by-step explanation:
Given:
measure of an intercepted arc = 86°
Center Angle = 86°
measure of the inscribed angle creating the intercepted arc= (3x+4)°
Angle Inscribed in arc = (3x+4)°
To Find:
value of x = ?
Solution:
Inscribed Angle Theorem:
The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
Substituting the values we get
Therefore the value of x is 13.
