Answer:
2sin50 cos20
Step-by-step explanation:
We need to write sin (70) + sin(30) as a product. The formula used here is :
Here, A = 70 and B = 30
So,
So, the value of sin (70) + sin(30) is 2sin50 cos20. Hence, the correct option is (c).
Answer:
x =
Step-by-step explanation:
Given
x + + (x - 1) =
Multiply through by 10 ( the LCM of 2 and 5 ) to clear the fractions
10x + 15 + 10(x - 1) = 8
10x + 15 + 10x - 10 = 8
20x + 5 = 8 ( subtract 5 from both sides )
20x = 3 ( divide both sides by 20 )
x =
