Answer:

X=9

Step-by-step explanation:

So first you’ll get the variable on one side so you subtract 2x to x getting -x. That leaves you with 6=-x+15. Then you want to subtract 15 from 6 to get the variable alone. This makes -9=-x then you remove the subtraction symbols because they’re on both sides and if you divide x by -1 and -9 by -1 you get x=9 anyways. So that’s you’re answer x=9.

The diagram below shows the dimensions of a triangular park built in a new housing development. Two side lengths and one angle m
evablogger [386]
ANSWER

x = 50.5 \degree

EXPLANATION

We use the sine rule for solving triangles.

This is given by the formula,


\frac{ \sin(A) }{a}  =  \frac{ \sin(B) }{b}  = \frac{ \sin(C) }{c}


From the triangle,

\frac{ \sin(x) }{60}  =  \frac{ \sin(40) }{50}

We multiply both sides of the equation by 60 to get,

sin(x)  =  \frac{ 60\sin(40 \degree) }{50}


sin(x)  = 0.7713



We solve for x to obtain,

x = arcsin(0.7713)


x = 50.475

To the nearest tenth, we round to one decimal place to get,

x = 50.5 \degree
