Answer:
SAS
Step-by-step explanation:
The triangles are compared with 2 sides and 1 angle. So, it is SAS
Answer:
Solution given:
sin y = -4/5
p/h=4/5
p=4
h=5
b=√{5²-4²)=3
cos y = b/h=-3/5
again
cos x=12/13
b/h=12/13
b=12
h=13
p=√(13²-12²)=5
sin x=p/h=5/13
now
sin[x-y]=sinxcosy-cosxsiny
=5/13×-3/5-(12/13×-4/5)=33/65 is your answer.
6 lessons per week multiplied by the number of weeks in a year
6 x 52 = 312
total - 5 missed
312 - 5 = 307 dance lessons
An equation for your earnings is 56 = 8h
An equation for your friend's earnings is 36 = 4h
To get your pay per hour divide each side by 8 to get $7 per hour.
To get your friend's pay per hour divide each side by 4 to get $9 per hour.
Hope this helps!
