7/8 = <span>0.875
3/4 </span><span>= 0.75
</span>0.875 - 0.75 = 0.125
Answer. 0.125
Answer:
- ∠ZXW and ∠ZXY are right angles
Step-by-step explanation:
- <em>Two right triangles are congruent if the hypotenuse and one corresponding leg are equal in both triangles</em>
<u>We have indication of:</u>
Missing information is just confirmation that both of them are right triangles
<u>This is:</u>
- ∠ZXW and ∠ZXY are right angles
Correct answer option is B
So for the algorithm you would use proportions like 3 and 1/8 over x = 1/4 over 1 hr. So you multiply 3 and 1/8 by 1 and divide by 1/4.
The answer is <span>C. $69,740 because 350*12+45*12+65,000=$69,740</span>
The given identity sin(x+ y) - sin (x- y) = 2 cos x sin y has been verified
The identity is
sin(x+ y) - sin (x- y) = 2 cos x sin y
Here we have to use the trigonometric function
Consider the right hand side of the equation
We know
sin (x+ y) = sin x cos y + cos x sin y
sin (x-y) = sin x cos y - cos x sin y
Then
sin(x+ y) - sin (x- y) = sin x cos y + cos x sin y - (sin x cos y - cos x sin y)
= sin x cos y + cos x sin y - sin x cos y + cos x sin y
Eliminate the terms
= cos x sin y + cos x sin y
= 2 cos x sin y
Hence, the given identity sin(x+ y) - sin (x- y) = 2 cos x sin y has been verified
