1.Given the rotation of triangle ABC shown below, determine the counter-clockwise angle of rotation that occurred about point D. Show all relevant lines and measurements you made to determine your answer. A) 180°
B) 90°
C) 130°
D) 50°

D. 50º

Step-by-step explanation:

According to the image below attached, blue lines represents line segments and , the red line creates a right angle regarding (90º), where green line creates a flat angle with the same respect (180º). The angle between and is less than 90º and 180º, meaning an acute angle. Therefore, the right answer is D.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
