Answer:
3/10
Step-by-step explanation:
mom = 35 when girl is born
girl = 0 when born
after 15 year
mom = 35 + 15 = 50
girl = 0 + 15 = 15
fraction = girl / mom = 15/50 = 3/10
It is a to the tenth power.
The correct answer is B.
Answer:
A and B
Step-by-step explanation:
i plugged them all into my graphing calc.
-10=20
1=20
-2= -28
20=1160
-2= -28
-1= -16

Answer: Choice B</h3>
angle B = 118, a = 17, c = 18
==========================================================
Explanation:
Use the given angles to find angle B.
A+B+C = 180
B = 180-(A+C)
B = 180-(30+32)
B = 118
Now use the law of sines to find side 'a'
Make sure your calculator is in degree mode.
a/sin(A) = b/sin(B)
a/sin(30) = 30/sin(118)
a = sin(30)*30/sin(118)
a = 16.9885507603356
a = 17
Follow similar steps to find side c
c/sin(C) = b/sin(B)
c/sin(32) = 30/sin(118)
c = sin(32)*30/sin(118)
c = 18.005120638611
c = 18
Step-by-step explanation:
L.H.S
tanA * cosecA
=sinA/cosA * 1/sinA
now cancel sinA and sinA
then,
1/cosA
= secA
= RHS
hence proved
