Answer:

m∠D = 29°

Step-by-step explanation:

First, notice that ΔSTU and ΔDEF are similar triangles.

For instance, for side ST and DE, the scale factor is:

\displaystyle k=\frac{6}{15}=\frac{2}{3}

Likewise, for TU and EF and SU and DF, the scale factor reamins that same:

\displaystyle \frac{10}{4}=\frac{2}{5}\text{ and } \frac{8}{20}=\frac{2}{5}

By SSS Similarity, ΔSTU ~ ΔDEF.

Note that our similarity statement states that ∠S corresponds to ∠D.

So, ∠S = ∠D.

Since the angles remain the same in a scaled factor and ∠S measures 29°, ∠D is also 29°.

Answer:

m<D = 105

Step-by-step explanation:

So, Triangle STU and DEF are similar triangles, because their corresponding side lengths have the same ratio.

For example FD can be multiplied by 2.5 to get SU, and EF can be multiplied by 2.5 to get TU, and ED can me multiplied by 2.5 to get 15.

Anyways, since the two triangles are similar, they have the same angle measures, meaning that angle D can be found by subtracting 46 and 25 from 180 degrees to find the missing angle, which is 105 degrees. I hope that helps.

Inez waters her plants every two days. She trims them every 15 days. She did both today. When will she do them both again?
shtirl [24]

The answer is 30 days.

The solution for this is to find the least common multiple. By getting the multiple of both numbers.

Multiples of 2:  2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40…..

Multiples of 15: 15,30,45,60,75……..

The Least Common Multiples of 2 and 15 is 30. So, Inez will do them both again in 30 days.

The least common multiple (LCM) of two numbers is the smallest number that is multiple by the both number.

For each parallelogram find the length of the base or height the first parallelogram has the area of 60 meters square the base i
Lynna [10]

Answer:

  5 m

Step-by-step explanation:

You know the area of a parallelogram is the product of its base length and height:

  area = base × height

Fill in the given values, and solve for height:

  60 m² = (12 m) × height

  (60 m²)/(12 m) = height = (60/12) m

  height = 5 m

The height is 5 meters.
