First, you set up your equation then you put the pieces together to get the answer
Where ever u see a y change it to an x
3x+2(x)=20
5x=20
x=4
Answer:
m= 11.4
Step-by-step explanation:
13.5= m+2.1
Subtract 2.1 to both sides
13.5= m+2.1
-2.1 -2.1
11.4= m
A^2 + B^2=C^2 so there for the hypotenuse (13^2) - (5^2) will give you the last side
<u>Answer</u>
18.5 m²
<u>Explanation</u>
The figure is a sector of angle 85° and of radius 5 m.
The area = θ/360 × π × r²
= 85/360 × 3.14 × 5²
= 18.5347
The answer to one decimal place is 18.5 m²
