Answer:
Step-by-step explanation:
By the congruent complements theorem , we know that angle 1 is congruent to angle 3. The measure of angle 1 equals the measure of angle 3 by the definition of congruent angles. Then, using the substitution property, the measure of angle 3 is 35 degrees.
Answer:
Step-by-step explanation:
are blue shirts.
Since the second blue shirt is different, there is no replacement.
x = 
Simplified: =
Answer:
the median is 6 and the mean is 8.375
Step-by-step explanation:
first you have to arrange the numbers from least to greatest the median is the middle number which in this case there are two but both of them are 6 so the median is 6 and for the mean you just average by adding it all together then divide by the total
10.
Answer: 42° and 138°
Steps: First find value of x by adding both equations and setting them equal to 180°:
3x + 12x - 30 = 180
15x - 30 = 180
15x = 210
x = 14
Next, put value of x into equations to find the angle:
3x
3(14)
42°
12x - 30
12(14) - 30
168 - 30
138°
11. Answer: 28°
Steps: Complementary angles add up to 90°, so subtract 62° from 90° to find its complementary angle.
90 - 62 = 28
12. Answer: Corresponding angles are congruent.
