Answer:

3. d = 15 ; c° = 90°

4. s = 12 ; t° = 71°

Step-by-step explanation:

Figures are similar.

Therefore:

3. In the rectangles one is 3 times bigger than the other. each side is multiplied by 3.

We can find d : 5*3 = 15

Also, the angles are equal 90° angles.

4. The other shape is similar but it is up side down.

one is 6 times bigger than the other. We can fins by multibliying the same side of the small shape by 6 : 2*6 = 12

The angle t° is the same angle oposite to the 90° angle but in the right position. Remember the Shape is up side down,

Therefore: t° = 71°

The sum of three consecutive integers is 141. what is the smallest integer

Dafna1 [17]

Integer 1 = n
integer 2 = n + 1
integer 3 = n + 2

n + (n + 1) + (n + 2) = 141
3n + 3 = 141
3n = 141 - 3
3n = 138
n = 138/3
n = 46 --(1st integer)

n + 1 = 46 + 1 = 47 --(2nd integer)
n + 2 = 46 + 2 = 48 --(3rd integer)

so the smallest integer is 46
