Answer:
(a) x = 
(b) x = 
Step-by-step explanation:
A. sum of angles in a polygon = (n - 2) 180
The polygon given is an irregular pentagon, where n = 5
So that;
sum of angles in a pentagon = (5 - 2) 180
= 3 x 180
= 
Thus,
x + 90 + 76 + 110 + 136 = 
x + 412 = 
x =
- 412
x = 
B. The polygon given is an irregular pentagon, where n = 5.
Let the supplementary angle with angle 38 be represented by y,
y + 38 = 180
y = 180 - 38
= 
y = 
Let the supplementary angle with x be represented by z, so that;
z + 72 + 120 + 100 + 142 = 
z + 434 = 
z =
- 434
= 
z = 
But, x + z = 
Then;
x +
= 
x =
- 
= 
x = 
Answer:
d < 7/9
Step-by-step explanation:
Add 7d +10
7 > 9d
Divide by 9
7/9 > d
Answer:
Question 3 of 10 The answer should be 7
Step-by-step explanation:
The reason is because if it is out of 100 7/100 is still 7%
Answer:
About 16 years
Step-by-step explanation:
First we need to figure out 5.25% of 12000
5.25 x 0.12000 = 0.63
Then we move the decimal
630
Then we need to figure out how many years it will take to reach $22000
Since we already owe $12000, we can just divide using $10000 because 10000 + 12000 = 22000
10000/630 = 15.87
Which is about 16 years
