Answer:
36°, 36° and 108°
Step-by-step explanation:
let the equal angles be x then the third angle = 3x
The sum of the 3 angles in a triangle = 180°, thus
x + x + 3x = 180, that is
5x = 180 ( divide both sides by 5 )
x = 36
and 3x = 3 × 36 = 108
The 3 angles are 36°, 36° and 108°
Answer:
p = 2.7x - 20
p(90) = $223
Step-by-step explanation:
revenue → f(x) = 3x ,where x is the number of downloads.
the statement “Your profit p is $20 less than 90% of the revenue for x downloads”

………………………………
the profit for 90 downloads :
= p(90)
= 2.7×(90) - 20
= $223
I am not 100% positive but from what I remember learning I think the answer you are looking for on the first question is C.
