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: 56
Step-by-step explanation:
20×3 is 60 and if Sarah counted 45 beats in 20 seconds you'd multiply 45 by 3 so it would be 135.
Step-by-step explanation:
2/5+2/4 (find common denominator)
The common denominator is 20
2/5 is 8/20 (multiply by 4)
2/4 is 10/20 (multiply by 5)
8/20+10/20 is 18/20
If you simplify 18/20 this would by 9/10 if you divide by 2
so the total is 18/20 or 9/10 simplified
Hope this helps!!!!
Have a nice day :)
