Answer:
16 degrees
Step-by-step explanation:
<u><em>The question is</em></u>
Find the measure of angle R
we know that
An exterior angle of a triangle is equal to the sum of the opposite interior angles
so
In this problem
we have
substitute
Answer:
At a price of $p, a quantity, q, of the item is sold.
If q = f(p)
(a) f(150) = 2000 means at price = 150$, the number of items sold is 2000
(b) f'(150) = -25 means rate of sale is negative or the number of items sold will be decreases in future
Answer:
∠ B = 54°
Step-by-step explanation:
Supplementary angles sum to 180°.
Sum A and B and equate to 180, that is
7x + 14 + 5x - 26 = 180, that is
12x - 12 = 180 ( add 12 to both sides )
12x = 192 ( divide both sides by 12 )
x = 16
Thus
∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°
Answer:
12
Step-by-step explanation:
2x (3) = 72 so 6x = 72 and so x = 12
