Step-by-step explanation:
The statement that justifies why ∠EBC measures 90° is that the sum of the measures of two complementary angles is 90 degrees.
<h3>What are
complementary angles?</h3>
The complementary angles are angles that when we find their sum it will be equal to 90 degrees and that is why its been regarded as the complementary angles.
We can see that m∠ABD and m∠DBC are complementary, because m∠ABD + m∠DBC=90°
Therefore, The statement that justifies why ∠EBC measures 90° is that the sum of the measures of two complementary angles is 90 degrees.

15 is the greatest common factor so it would be 15(5+4)
Answer:
There are 21.4285714 (21 or 22) questions
Step-by-step explanation:
15 / 70% = 21.4285714
21.4285714 * 70% = 15
21 * 70% = 14.7
22 * 70 = 15.4
Both 14.7 and 15.4 round to 15
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
Slope = (4-7)/(7-1)
Slope = -3/6
Slope = -1/2
