Answer:
8) 10 m 9) 26 in 10) 51 m 11) 50 ft 12) 19.4 cm 13) 177.9 m 14) 40 15) 12 16) 14.7 17) 12.1
Step-by-step explanation:
You may solve the problems by using the Pythagorean Theorem which states that c^2 = a^2 + b^2, or in other words, the hypotenuse squared is equal to the sum of the legs squared.
Hope this helps! :-)
Answer:
step 2
and then also in step 3 compensating the error in step 2
Step-by-step explanation:
I think I just answered this for another post.
sin(a - b) = sin(a)cos(b) - cos(a)sin(b)
so, step 1 is correct :
sin(A - 3pi/2) = sin(A)cos(3pi/2) - cos(A)sin(3pi/2)
but step 2 suddenly and incorrectly switched that central "-" to a "+".
yes, sin(3pi/2) = -1, but that is still an explicit factor in step 2. so it was not used to flip the central operation from subtraction to addition, and therefore this change was a mistake.
then, in step 3, another error was made by just ignoring the "-" sign of "-1" and still keeping the central "+" operation. this error compensated for the error in step 2 bringing us back by pure chance to the right result.
I believe the right anwser is c
Hello there!
8 - 2x = -8x + 14
Let's start by subtracting 8 to both sides
8 - 2x - 8 = -8x + 14 - 8
-2x = -8x + 6
Let's add 8x to both sides
-2x + 8x = -8x + 6 +8x
6x = 6
Divide both sides by 6
6x/6 = 6/6
x = 1
The correct answer is option D
I hope this helps!
