Answer:
the first one
Step-by-step explanation:
angle L congruent to angle P
Answer:
a. 10 + 2.50x
b. 60
c. 100
Step-by-step explanation:
a. 10 + 2.50x
b. 10 + 2.50(20)
= 10 + 50
= 60
c. 260 = 10 + 2.50x
250 = 2.50x
250/2.50 = x
x = 100
500<span> ≥ 51x
(65-14 = 51 dollars a week)
500</span><span> ≥ 51x
/51
9.8 weeks -> round up you can't have .8 of a week... 10 weeks.
Amy must work at least 10 weeks to make 500 dollars </span>
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.
