Answer:
0.74
Step-by-step explanation:
We can isolate x, getting 9.2x - 1.9x = -1 + 6.4
We can then simplify, getting 7.3x = 5.4, which we can solve by dividing both sides by 7.3:
x = 5.4 / 7.3 = 0.74

1,200+40x=400+50x
800+40x=50x
800=10x
x=80
Answer:
x=y

3 times 2 is 6
Step-by-step explanation:
Answer:
Step-by-step explanation:
2: exterior and opposite
3:supplementary
5: angles and equal
6: supplementary
When a perpendicular is dropped from the right-angle (C) to the opposite side AB, the metric relations apply:
BD*BA=a^2 ..........................(1)
AD*AB=b^2...........................(2)
BD*DA=DC^2........................(3)
Given AD=6, AB=24, using metric relation (2) above, we have
b^2=6*24=144
=>
b=sqrt(144)=12
By the way, we conclude that this is a 30-60-90 triangle because b/AB=(1/2)=sin(B) => B=30 degrees.
Answer: b=12
