Find the value of x that makes the shape a rhombus.

Mathematics
1 answer:
goldenfox [79]3 years ago

Given:

CDEF is a rhombus.

To find:

The value of x.

Solution:

We know that the diagonals of a rhombus are angle bisectors because they bisect each vertex angle.

5x+1=8x-20

5x-8x=-1-20

-3x=-21

Divide both sides by -3.

x=\dfrac{-21}{-3}

x=7

Therefore, the value of x is 7.

Which of the following equations could be solved to determine the length of RS?
stich3 [128]

Answer:

\frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}

Step-by-step explanation:

Given:

S = 52.5°

s = QR = 7

Q = 80°

q = RS = ?

Required:

Equation that could be used to find the length of RS

Solution:

We would need the law of Sines which is given as:

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

Applying the Law of Sines, we would have the following equation:

\frac{Sin(Q)}{q} = \frac{Sin(S)}{s}

Plug in the values

\frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}

Therefore, the equation that can be used to determine the length of RS is \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}
