Answer:
BC =21.03540021
Step-by-step explanation:
We know the measure of angle B since the sum of the angles of a triangle add to 180
A + B+ C = 180
61+ B + 12 =180
B = 180 - 12 -61
B =107
Then we can use the law of sines to find BC
sin B sin A
-------- = -------------
AC BC
sin 107 sin 61
-------- = -------------
23 BC
Using cross products
BC sin 107 = 23 sin 61
BC = 23 sin 61/ sin 107
BC =21.03540021
Ray is the answer,hope this helps
Answer:
f(0)=4
Step-by-step explanation:
f(0)=4*9^0=4*1=4
The reason is the gotter of the right angle is 12
In its normal way, For example: 214, Write it in the way it is Usually written.
