Answer:
True
Step-by-step explanation:
Parallel lines always have the same slope, so therefore the answer is True
The area of the metal strips:
A = L * W , where L stays for length and W stays for wirth.
A = 11 ft * 2 ft ;
A = 22 ft^2.
If it costs $6 per foot:
Total cost = 22 * 6 = $132.
Answer: The total cost of a metal strip is $132.
Answer:
sin 5x cos x - cos 5x sin x = sin(4x)
Step-by-step explanation:
Given that the trigonometric expression,
sin 5x cos x - cos 5x sin x
Here we use the "sum and difference formulas"
Sum and Difference Formulas
sin(A+B)=sin A cos B + cos A sin B
sin(A-B)=sin A cos B - cos A sin B
cos(A+B)=cos A cos B - sin A sin B
cos(A-B)=cos A cos B + sin A sin B
So,
sin 5x cos x - cos 5x sin x = sin (5x - x)
sin 5x cos x - cos 5x sin x = sin(4x)
That's the final answer.
Answer:
the angles are 35⁰, 70⁰ 75⁰
Step-by-step explanation:
the three angles are = x⁰ +2x⁰+(2x+5)⁰= 180⁰
5x+5= 180
5x= 175
x= 175/5= 35⁰
2x= 70⁰
2x+5= 75⁰
