Answer:
B
Step-by-step explanation:
AC = x, CD = 2x cause of 30° angle. Use pythagoras then
Cos theta = 75/115
theta = cos^-1 (75/115)
theta = 49.2 degrees
Answer:
x= 48
Step-by-step explanation:
Multiply 8 by 6 to get x by itself and you get your answer.
Find the prime factorization
45=3*3*5
60=2*2*3*5
GCF=3*5=15
45=3*15
60=4*15
remember
ab+ac=a(b+c) so
45+60=15(3)+15(4)=15(3+4)=15(7)=105
