To solve this you need to use the formula for Chord-Chord length. You need to know it, it is ab=cd. with this, we can plug numbers in.
a=30
b=x+1
c=2x-6
d=21
So our new equation is:
30(x+1)=21(2x-6)
30x+30=42x-126
156=12x
x=13
This isn't what the question is askign for though, it wants YZ
Which is A+B or 30+x+1 or 21+13=34. 
YZ=34

How do I calculate the shaded area of this shape ?
TEA [102]

SOLUTION:

We are to calculate the shaded area of the given shape.

CONCEPT:

This is a triangle that a rectangle was cut out from.

To calculate the shaded area of the given shape, we are to find the area of the triangle and then subtract the area of the recangle that was cut out.

\begin{gathered} \text{Area of Triangle:} \\ A\text{ = }\frac{1}{2}\text{ base }\times\text{ height} \\  \\ A\text{ = }\frac{1}{2}\text{ }\times\text{ 6m }\times7m\text{ } \\  \\ A=21m^2 \end{gathered}\begin{gathered} \text{Area of Rectangle:} \\ A=L\text{ }\times\text{ W } \\ A\text{ = 4m }\times\text{ 2m} \\ A=8m^2 \end{gathered}

The shaded area = Area of the triangle - Area of the rectangle

\begin{gathered} \text{Shaded area = 21 m}^2-8m^2 \\ \text{Shaded area = 13 m}^2 \end{gathered}

Math Problem: Convert
Sever21 [200]

Answer:

135°

Step-by-step explanation:

To convert from radians to degrees

degree = radian × \frac{180}{\pi }

Thus for \frac{3\pi }{4}

degree = \frac{3\pi }{4} × \frac{180}{\pi } ( cancel the π  )

            = \frac{3(180)}{4}

            = \frac{540}{4}

            = 135°

What is the equation of the line that passes through the point (-7,-4) and has an undefined slope?
slava [35]

Answer:

When the slope is UNDEFINED, that means the denominator of the slope formula is ZERO .

Slope formula = (y2 - y1)/(x2 - x1), and the graph is a VERTICAL line and the equation of the line is x =7 . Point (7, -4) is a point on the line.

Hope this helps...
