Answer:
=5.1 units
Step-by-step explanation:
To use the sine rule to find the length of c we first need to find the angle at C.
C=180-(13+12)
C=180-25
C=155°
a/Sin A=c/Sin C
Calculating for the value of c using the sine rule:
12/Sin 13=c/Sin 155
c=12 sin 155
=5.07 units
Thus to 1 decimal places, the value of c is 5.1 units.
Answer:
G, the second option
Step-by-step explanation:
A triangle's degrees all adds up to 180.
45 + 60= 105 degrees
180-105= 75 degrees
<u>that in which makes </u><u>z=75 degrees.</u>
Since z is sharing a straight angle, which is 180 degrees
180-75= 105 degrees.
<u>Therefore, </u><u>w=105 degrees</u>

The answer is -0.48.
First, you multiply 1.2 to 4 to get 4.8. Then, since the 4 wasn't 4 but 0.4, you have to divide 4.8 by 10 to get 0.48. Finally, since -1.2 is negative, you put a negative sign in front of 0.48 to get -0.48.
$24 times 10 is $240 and $6 times 100 is $600 so 240+$600 is $840 then $840 devided by 4 is $210.
