Answer:
3rd option 20
Step-by-step explanation:
20+2x+6x = 180
8x+20= 180
8x= 180-20
x=20
They will have the same slope.
We have that since the chords are equal, the arcs are equal too. Hence AB=RS. We also have that AB=AR+RB and RS=RB+BS. By equating these two, we have that AR=BS. Hence BS=55 degrees. Substituting back, since we know RB and BS, we get: RS=55+66=121 degrees
The rate of change is +2 or 2 over 1 or 2/1
Answer:
The answer is D
Step-by-step explanation:
change 2 5/6 to 2 10/12 by multiplying top and bottom by two. Then change 3 1/4 to 3 3/12 by multiplying the top and bottom by 3, this gives these fractions the same denominator. Then add these and get 5 13/12 which will be 6 1/12
