It is a rule that alternate angles are equal, so using this fact, we can say that:
3x + 17 = x + 53
- x
2x + 17 = 53
- 17
2x = 36
÷ 2
x = 18
Which means that your answer would be B. x = 18
I hope this helps!
Im pretty sure the answer is the second one
Answer:
, 
, and 
.
Step-by-step explanation:
What is a rational number? By definition, a rational number can be represented as the fraction of two integers.
The goal is to find three fractions in the form 
between 
and 
.
.
At this moment, there doesn't seems to be a number that could fit. The question is asking for three of these numbers. Multiple the numerator and the denominator by a number greater than three (e.g., five) to obtain
.
Since 
and 
can be any integers, let 
.
.
.
Possible values of are 26, 27, and 28. That corresponds to the fractions
, , and .
These are all rational numbers for they are fractions of integers.
The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you <u>18=b</u>.
To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.
