Answer:
c (6)
Step-by-step explanation:
by the corresponding angles postulate, the angle above 20x-5 will be 65°.
20x - 5 + 65 = 180 <em>they are supplementary angles (angles that add up to 180°)</em>
20x + 60 = 180
20x = 120
x = 6
Answer:
BC = 19.78
Step-by-step explanation:
using sin(x) rule
sin(54)= 16/BC
sin(54)=0.80
∴0.80=16/BC (divied both side by 0.80)
BC=16/0.80 =19.78
