Answer:
do you have a picture of the problem as well?
Step-by-step explanation:
For #18
you would divide 3y over 3 witch would cancel out then you would divide 9.5 over 3 and you would get (3.16) i think
Step-by-step explanation:
In figure:
∠PRT+∠RTP+∠TPR=180
O
(angle sum property of triangle)
⇒x+(180
O
−∠RTQ)+60
O
=180
O
(linear pair)
⇒x+(180
O
−97
0
)+60
o
=180
O
⇒x=31
o
Now, ∠PRT+∠TRQ+∠QRS=180
O
(angle of straight line)
⇒x+48
o
+y=180
O
⇒31
o
+48
o
+y=180
O
⇒y=101
0
8÷1/3=24 so the answer is C
