The slope is 2x. In other words 2/1
C=10, C=90°, B=30°, A+B+C=180°
A+30°+90°=180°⇒A=60°
cos30°=a/c
cos30°=a/10⇒a=cos30°*10
a<span>≃8.6602
c²=a²+b²⇒b²=c²-a²
b²=10²-8.6602²⇒b²=25
b=5

Answer:mutiply not sure
Step-by-step explanation:
4) i believe the answer is B. angle bisector, since the line AD bisects angle BAC
5) It is R and S, and i believe the answer is C, converse of alternate interior angles theorem
hope this helps
