Wouldnt that be zero cuz they used more then they started of with?
Answer:
114°
Step-by-step explanation:
<A=<B (corresponding angles)
6x+12=3x+63
6x-3x=63-12
3x=51
Dividing both sides by 3
x=17
Now
<A=6x+12
=6(17)+12
=102+12
=114°
Answer:

Step-by-step explanation:
Given
tan x =
, then
x =
(
) = 60° ← related acute angle
Since 180° < x < 270° and tan x > 0 then x is in third quadrant
x = 180° + 60° = 240°
and
sin(x - 210)°
= sin(240 - 210)°
= sin30°
= 
5×3=15 so 15÷ 3=5, The answer to this question would be is 5.
