Answer:
B
Step-by-step explanation:
angle 5 and angle 7 will add up 180
since angle 5 is congruent to angle 1 then angle 5 equals 120
angle 7 will come out to 60 degrees
180-120=60
Answer:

9 years ago, she was 8 years old. So, you'd take her age then + number of years passed. So, 8+9=17.
As scientists conduct their research, they make observations and collect data. The observations and data often lead them to ask why something is the way it is. Scientists pursue answers to these questions in order to continue with their research.
Answer:
- resistance: (2r +5)
- current: (3i +4)
Step-by-step explanation:
The factors of the given expression are ...
6ir +15i +8r +20 = (3i +4)(2r +5)
Which factor is current and which is resistance is not clear. Usually, resistance is referred to using the variable r, so we suppose the expressions are supposed to be ...
resistance: (2r +5)
current: (3i +4)
