Is this statement true or false?
Fitness levels can be measured by simple tests, such as counting the number of crunches you can do in two minutes.
Recall that 2sin(x) cos(x) is actually equal to sin(2x).
We can prove this by expanding sin(2x) to sin(x + x).
sin(x + x) = sin(x) cos(x) + cos(x) sin(x) = 2sinxcosx
Thus, 2sin(x/2)cos(x/2) can be rewritten in the form:
sin(2x/2), and this simplifies down to sinx.
Step-by-step explanation:
m<5=180-m<4 (linear pair)
m<5=180-125 = 55°
m<5=m<1 ( alternate angle)
therefore, m<1 = 55°.
hope this helps you.
