PYTHAGORAS THEOREM
Answer:
15 days
Step-by-step explanation:
Since he used both of the weights today, he will only do both on the day they come together.
weights: 3 days, 6 days, 9 days, 12 days, 15 days
machine: 5 days, 10 days, 15 days
Because the numbers both were the same on 15 days, then that is when he will do both of them
I hope you are looking for these answer choices as you have not posted the choices. Therefore, I have a similar question with these answer choices.
a). tan² x - 1 = sec²x
b). 4 cosxsinx = 2cos + 1 -2sinx
c). tanx cosx cscx = 1
d). 1- tanx tany = cos(x+y) ÷ cosx cosy
<span>Options B, C, D are correct because, for all them, left-hand side equals to the right-hand side for x = 0.
The option A)
</span>tan² x - 1 = sec²x<span> is not true.
since x = 0
Therefore,
The Right hand side would be:
</span>tan² x - 1 = sec²(0)<span>
= 1
The Left hand side would be:
</span> tan² x - 1 = tan² (0) - 1
= 0 - 1
= -2
Therefore,
Both sides are not equal so it's not a trigonometric identity.
Answer:
The answer is the second one
Step-by-step explanation:
Answer:
x=23°
Step-by-step explanation:
93°+(3x+18)°=180°
93°+3x+18°=180°
111°+3x=180°
3x=180°-111°
3x=69°
x=69°:3
x=23°
