Quadrilateral SQUA is a square with sides measuring 25mm. Quadrilateral AQER is also a square.What is the length diagonal RQ
svet-max [94.6K]

The square has 4 sides of the same measure.

If square SQUA has a side measuring 25 mm, it means side QU measures the same.

Also, if quadrilateral AQER is a square two, then its diagonals bisect each other, then QU is equal to UR.

Thus, QR measures:

\begin{gathered} QR=QU+UR \\ QR=25\operatorname{mm}+25\operatorname{mm} \\ QR=50\operatorname{mm} \end{gathered}

The answer is 50 mm

Does anyone know how to solve this?
MrRissso [65]

9514 1404 393

Answer:

Step-by-step explanation:

The tangent of the angle can be found using the identity for the tangent of the difference of angles.

  tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))

The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.

  tan(α) = -2/3

  tan(β) = 4/7

  tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))

  = (-14-12)/(21 -8) = -26/13 = -2

Then the magnitude of the angle between the vectors is ...

  arctan(2) ≈ 63.43°

A building has a length of 40 m. The length of its scale model is 25 cm. What scale factor was used to make the scale model?
Marizza181 [45]
The answer is 1 cm = 1.6m. We know this because the scale model was 25 cm and the building was 40m. To simplify, our proportion is 40 meters /25 centimeters to x meters/1 centimeter. 40/25= 1.6, so we can say that x (the scale factor) is 1 cm to 1.6 m.
