in the right triangle shown, A= 30° and BC =6 How long is AB?Answer exactly using a radical if needed.
1 answer:
Answer: 10.4
Step-by-step explanation:
According to the right angle triangle, the longest side is the hypothenus, d side facing the angle is the opposite and the other side is the adjacent
So we this we will use tan
Tan 30= opp/adj
Tan 30= 6/x
Cross multiply
Xtan30= 6
X= 6/tan 30
X= 6/1/square root of 3
X= 6 x square root of 3
X= 10.39 ~ 10.4

Answer:
or
Step-by-step explanation:
We use casework on when and when
.
For the first case, , we add 9 to both sides to get
.
Dividing both sides by 3 gives
For the second case, , we add 9 to both sides to get
.
Dividing both sides by 3 gives
.
Checking both cases, we plug in and
.
For the first case, we have , which satisfies the equation.
For the second case, we have , which also satisfies the equation.
This gives us two solutions to the equation; and
.
