If CX = 5 units, then DZ = ___ units
gulaghasi [49]

Answer:

DZ=4\ units

Step-by-step explanation:

we know that

If CD is parallel to XZ

then

Triangle XYZ is similar to Triangle YCD

therefore

The ratio of their corresponding sides are equal

\frac{XY}{CY}=\frac{ZY}{YD}

we have

CX=5\ units, CY=25\ units, YD=20\ units,

XY=CX+CY

XY=5+25=30\ units

ZY=YD+DZ

ZY=20+DZ

substitute the values

\frac{30}{25}=\frac{20+DZ}{20}

20\frac{30}{25}={20+DZ}

24={20+DZ}

DZ=4\ units

Find the missing side. Round your answer to the nearest tenths.<br><br> X=
Lapatulllka [165]

Answer:

   16.5 ≈ x

Step-by-step explanation:

We have a right triangle where we know 1 side, 1 angle and we need to find another side. We can use trigonometric functions to find the missing side.

The tangent function definition is

tan α = opposite side/ adjacent side

In our problem

   tan 70° = x/ 6, multiply both sides by 6 to isolate x

6 · tan 70° = x, use the calculator (make sure is set in degrees)

    16.4848 ≈ x , round to the nearest tenths

         16.5 ≈ x

The straight lines passing through these pairs of points (2, 5) and (4, 7) ,(−4, 2) and (1, 7) are,
Taya2010 [7]

Answer:

The line passes (2, 5) and (4, 7) has slope:

S = (7 - 5)/(4 - 2) = 2/2 = 1

The line passes (1, 7) and (-4, 2) has slope:

S = (2 - 7)/(-4 - 4) = 5/-5 = -1

The multiplication of two slope is  1 x (-1) = -1

=> Two lines are perpendicular

Hope this helps!
