Answer:
answer is r=21
Step-by-step explanation:
multiply 1.5 with 14
Adjacent side to angle 60º=2/3
opposite side to angle 60º=b
hypotenuse=a
cos 60º= adjacent side / hypotenuse
cos 60º=(2/3) / a
a=(2/3) / cos 60º=(2/3) / (1/2)=4/3
tan 60º= opposite side / adjacent side
tan 60º=b / (2/3)
b=(2/3)*tan 60º=(2/3)* √3=2√3 /3
Answer:
a=4/3
b=2√3 /3
