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 1 3/5 × 40=64
Step-by-step explanation:
4×2/5=1 3/5 4×10=40
Answer:
slope: -1/2
y-intercept: 2
Step-by-step explanation:
y=mx+b is the equation to a linear function
m=slope
b=y-intercept
In this case, -1/2 is the m, and 2 is the y-intercept.
