Answer:
30, 20
Step-by-step explanation:
Multiply a big number with 3. Such as 30, or 20.
30 x 3= 90
20 x 3=60
The value of y = 40.
5x = 40
x = 8
180 = 40 + 40 + (2y + 20)
40 = y
Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° =
=
= 
Multiply both sides by 7, thus
AC = 7sin40° → A
