(2 x + 1):15=(x-1):7
7(2x+1)=15(x-1)
14x+7=15x-15
14x-15x=-15-7
-x=-22
x=22

Let's solve for value of values of x and y ~
According to Angle sum property of triangles :




Now, solve for y ~




Now, by the results we got, we can conclude that :
The two triangles are not similar because 70 + 58 + x = 180 means x = 52° and 70 + 49 + y=180 means y = 61°
Answer:
4pi or 12.57
Step-by-step explanation:
Area = pi * radius^2
Area = pi * 2^2
Area = pi * 4
Area = 4pi or 12.57
