Answer:
C) △ABC is moved onto △A'B'C' after translating −16 units horizontally and 6 units vertically, and then reflecting across the x-axis.
Explanation: I did USA Test Prep.
Angle PTG = arccos((18^2 + 13^2 - 27^2) / (2 x 18 x 13)) = arccos(-236 / 468) = arccos(-0.5043) = 120 degrees.
The triangle is an obtuse triangle (because one of the angles is greater than 90 degrees) and a scalene triangle (because all the sides are not equal).
Answer:

Step-by-step explanation:
Cheryl is 17 years old now.
Step-by-step explanation:
Let,
Age of Cheryl = x
Age of Henry = 2x+6
In 10 years;
Cheryl's age = x+10
Henry's age = 2x+6+10 = 2x+16
The sum of ages is 77.

Dividing both sides by 3

Age of Cheryl = 17 years
Age of Henry = 2x+6 = 2(17)+6 = 34+6 = 40 years
Cheryl is 17 years old now.
