Answer:
54 degrees.
Step-by-step explanation:
So a fun fact is that the exterior angle is equal to the sum of the opposite two interior angles (at least within triangles).
Given this, set these values equal to each other to get the value of a.
d = a + b
2a = (a+10)+44
2a = a + 54
a = 54
The measure of the exterior angle is 54 degrees.
D. Juan's measurements are more accurate and more precise.
To find his answer you will find the distance between (60, 30) and (100, 30) (length). How far from 60 to 100. It is 40 feet. The x values are used to see the distance.
To find the height use (60, 30) and (60, 90). How far is it from 30 to 90? These are the y values This is 60 feet.
To find the perimeter add 60+60+40+40. The answer is 200 feet. You can show this as P=200 feet.
Answer:
About 22 times
Step-by-step explanation:
Unit Rate means the number of times Jake cleans his house PER WEEK.
Since he clean his house only 3 times per 7 weeks, we will have a number less than 1 (per week). To get unit rate, we divide the number of times (3) with the number of weeks (7). Thus:
Unit Rate = 
times in 1 week
Now, we can set up a ratio (2 fractions), equate them and solve for the unknown [let times he clean his house in 52 weeks be x]. Shown below:
To solve this, we cross multiply and use basic algebra and solve for x:
That's 22.29 times in 52 weeks (let's round and say 22 times).
