I'd draw it like this :P

READ BELOW:

But the thing is, lines do not have end points. Therefore you either mean line segment, or the question is mathematically incorrect.

(unless you name the line RT)

If XY = 5x-3 and XZ=44, find x and the value of YZ
mixer [17]

The midpoint of a line divides the line into equal halves.

  • <em>The value of x is 5</em>
  • <em>The value of YZ is 22</em>

<em />

Given that:

XY = 5x -3

XZ = 44

Y is the midpoint of XZ. So:

XZ = 2 \times XY

44 = (5x - 3 ) \times 2

44 = 10x - 6

Collect like terms

10x = 44 +6

10x = 50

Divide both sides by 10

x = 5

Recall that: Y is the midpoint of XZ

This means that:

YZ = \frac12 XZ

YZ = \frac12 \times 44

YZ = 22

Hence, the value of x is 5 and YZ is 22

Find the value of the angle θ rounded to 1 DP.<br><br> The diagram is not drawn accurately
ollegr [7]

Answer:

Find length opposite to 30deg

Opposite = tan(30)*42

= 24.2

Whole side = 24.2+10

Find angle of 0 + 30deg: (say x)

Tan(x) = 33.2/42

Arctan(0.79) = x

x = 38.3

The angle to find:

38.3-30:

8.3

The angle is 8.3deg.

If cos(x)=-1/4 and tan(x)&lt;0 what is sin(2x)​
nata0808 [166]

By definition of tangent,

tan(<em>x</em>) = sin(<em>x</em>) / cos(<em>x</em>)

so if tan(<em>x</em>) < 0, and we're given cos(<em>x</em>) = -1/4 < 0, then it follows that sin(<em>x</em>) > 0.

Recall the Pythagorean identity:

cos²(<em>x</em>) + sin²(<em>x</em>) = 1   →   sin(<em>x</em>) = + √(1 - cos²(<em>x</em>))

Then

sin(<em>x</em>) = √(1 - (-1/4)²) = √(15/16) = √(15)/4

Recall the double angle identity:

sin(2<em>x</em>) = 2 sin(<em>x</em>) cos(<em>x</em>)

Then

sin(2<em>x</em>) = 2 • √(15)/4 • (-1/4) = -2√(15)/16 = -√(15)/8
