The correct answers are A, B, D, and E
Answer:
17 cm
Step-by-step explanation:
By Pythagoras Theorem
Answer:
sum of angles = 40 + (8x + 4) + (3x + 4) = 180
Collecting all similar terms, the equation above becomes
11x + 8 = 140 ---> x = 12
Therefore. angle S = 3x + 4 = 3(12) + 4 = 40
C.
The negative (-) means that you are losing 17 of something.
in I and II you are also losing 17 things. I you are losing 17 dollars and II you are losing 17 yards. III, however, you are gaining 17 degrees so it is not the answer.
Answer:
20
Step-by-step explanation:
To make these parallel, 2 and 5 would have to be corresponding angles, meaning that they have equal angle measure:
3x-20=x+20
3x=x+40
2x=40
x=20
