Answer:
37.9°
Step-by-step explanation:
ΔABC is similar to ΔPQR, so ∠R ≅ ∠C.
Given AB = 7 and AC = 9, we can find m∠C using tangent.
tan C = AB / AC
tan C = 7 / 9
m∠C = 37.9°
m∠R = 37.9°
Answer:
D
Step-by-step explanation:
hello :
The last two digits of the number are divisible by 4
exemple :
5028 is divisible by 4 because that 28 is divisible by 4.
538 is not divisible by 4 because 38 is not divisible by 4.
Where’s the x in the equation?
4 students went abroad. 32 divided by 8 is 4. If you take 1 group of the 8 that is 4 students going abroad
An equation is formed of two equal expressions. The number of gigabytes that is used in a month so that the two phone plans cost the same amount is 11.6667 Gigabyte.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let c represent the cost of a phone plan, m represent the number of months, and g represent the number of gigabytes of data used each month.
Equation1: C = 40m + 3.5mg = (40+3.5g)m
Equation2: C = 75m + 0.5mg = (75+0.5g)m
Equating C,
(40+3.5g)m = (75+0.5g)m
40 + 3.5g = 75 + 0.5g
3g = 35
g = 11.6667 gigabyte of data per month
Hence, the number of gigabytes that is used in a month so that the two phone plans cost the same amount is 11.6667 Gigabyte.
