What is the length of BC approximated to the nearest tenth?


A.
11







B.
13







C.
14







D.
16

Answer 1

6x-50=x+5

Answer 2

6x-50=x+5
-x -x
5x -50 =5
+50 +50
5x=55

Answer 3

55 divided by 5 is ?

Ok

Answer 10

A 30°-60°-90° triangle has a hypotenuse with a length of 10. What is the length of the longer leg of the triangle?

Answer 11

a 5 b 5 cubed c square root 5 d 20

Answer 12

Rule for all 30°-60°-90° triangles:

1. The hypotenuse is twice the shorter leg.
2. The longer leg is sqrt3 times the shorter leg.

Answer 13

Note: For the first problem x = 11 (and not the answer). You need to find the length of BC by plugging in the x value.

Answer 14

2x10=?

Answer 15

20

Answer 16

What is the value of x?

Answer 17

please help

Answer 18

Im mot really sure i dont want to give you a wrong answer

Answer 19

it's alright i'm in the safe zone u can give a wrong one

Answer 20

\[6x - 50 = x + 5\]
\[5x = 55\]

As Ranga mentioned you need to evaluate the length of BC, all we did is find the value of x.
\[BC = x + 5 ==> BC = 55 + 5 = 60\]

Answer 21

For your second problem,
You use the sine function.

\[\huge \sin {\theta} = \frac{ opp }{ hyp }\]
\[\sin 60^{o} = \frac{ x }{ 16 }\]
Evaluate sin at 60 degrees, and then solve for x.

Answer 22

First problem. x = 11, BC = x + 5 = 11 + 5 = 16. Answer is D.

Answer 23

oh oops i made an error there , x = 11, >.<
