Let the age of Vera be 'x' years
So the age of Linda is '2x' years
Now Tanya is 4 less than 4 times Linda
So age of Tanya = 4(2x) -4 = 8x -4 years
So total age of Vera , Linda & Tanya
= x + 2x + 8x - 4
= 11x - 4
But it is 2 less than 9 times Vera's age
11x - 4 = 9x + 2
11x - 9x = 4+2
2x = 6
x = 3
So Vera's age = 3 years
Linda's age = 2(3) = 6 years
Tanya's age = 8x - 4 = 8(3) - 4 = 24-4=20 years
Tanya is 20 years old.

It would be angle 1. to explain complementary means it adds up to 90
Answer:
∠ B ≈ 41.81°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin B = 
= 
= 
, thus
B = 
( ) ≈ 41.81° ( to the nearest hundredth )
