If angle A and B are complementary that means,

Measure of angle A + Measure of angle B = 90°

(x+16)° + (x-12)° = 90°

x+16+x-12 = 90°

2x+4 = 90°

2x+4-4 = 90°-4 (Subtraction Property)

2x = 86°

2x/2 = 86/2 (Division Property)

x = 43°

So,

For the measure of angle A, Plug in the value of x

(x+16)° = 43+16 = 59° ( ANSWER)

Answer:

Step-by-step explanation:

Let x and y be the total number of questions in part 1 and part 2 exams respectively.

For part 1:

Number of correct question = 4/5 of the total number of question in part 1

$\Rightarrow 16=\frac{4}{5}\times x$

$\Rightarrow x=20$

For part 2:

Number of corrected question = 2/3 of total number of question in part 2

$\Rightarrow 16=\frac{2}{3}\times x$

$\Rightarrow x=24$

So, the total umbers of the questions on Stephanie's exam

=x+y

=20+24

=44

Hence, the total umbers of the questions on Stephanie's exam was 44.

Answer:

Well, Your best answer will be is 225° rotation. Because, The points A' and C' are tilted more than 180 degrees from the origin of rotation. If it were 90 degrees, the A' and C' would have been in the right side. So, The best answer will be is 225°. 

Hope That Helps!
