Answer:
Step-by-step explanation:
If angle 5 = 4x + 15, and angle 4 = 6x - 5, and angle 5 = angle 4, then:
4x + 15 = 6x - 5 and
20 = 2x so
x = 10. Now sub this back in for x in angle 5's expression:
angle 5 = 4(10) + 15 ---> 40 + 15 ---> angle 5 = angle 4 = 55 degrees
12
4/ 1/3=12
x=2 AB=hypotenus(h) angle ACB is 90
BC=p angle CAB is 30 also angle of refrence
sin[30]=p/h
(1/2)=x/4
2x=4
x=2
are there any options? or no
