These are vertical angles so the opposite angle would equal each other.
Let’s start by solving for x:
52=x-15
Add 15 to both sides:
x=67 degrees
Now let’s solve for y:
4y=128
Divide 4 to both sides:
y=32 degrees
If by decomposition you mean breaking it ino parts then
break it itno 2 triangles and 1 rectangle
left to right
triangle with base y and height h
h=10
y=3
area of traignel=1/2bh
aera=1/2(10)(3)
area=5(3)
area=15
rectangel of legnth x and height h
area=legnth timwe width
x=8
h=10
area=8 times 10
aera=80
last triangle
should be same as other sinces same base (y) and same height (h)
15
add
15+80+15=120
Answer: 60
Step-by-step explanation:
From the question, we are informed that 430 students were surveyed and 258 said that their favorite type of pet was a dog. The fraction/decimal of those that chose dog as their favorite pet will be:
= 258/430
= 3/5
= 0.6
Suppose that only 100 students were surveyed, the number of students that would say that a dog is their favorite types of pet will be:
= 0.6 × 100
= 60
Answer:
≈ 542,029 copies
Step-by-step explanation:
37,400 copies represents a 6.9% of the total copies sold to date.
Therefore; Copies sold to date will be 100%
Thus;
Total number of copies sold = (37,400/6.9)× 100
= 542,028.99 copies
<u>≈ 542029 copies</u>
