Answer:

39 feet

Step-by-step explanation:

Since the triangle is right we can use the tan ratio to find BC

tan 30° = \frac{opposite}{adjacent} = \frac{BC}{68}

multiply both sides by 68

68 tan 30° = BC ⇒ BC ≈ 39 feet ( to nearest foot )

A point, beginning at (0,0), undergoes the following composition of translation. Write an ordered pair for the points final posi
Fiesta28 [93]

Answer:

(-1,-5)

Step-by-step explanation:

Starting at (0,0), we perform the first translation:

T<5,-7> implies that we move the point 5 units to the right (in the x (horizontal) direction), and 7 units DOWN in the y <vertical) direction.

From there we do the second translation: T<-6,2>

which means: 6 units to the left (in the horizontal direction) which takes us to  "-1" for the x value, and 2 units up (vertical) which takes us to -5 for the y value.

Therefore the new location is (-1,-5)

Someone please help me
pentagon [3]

Answer:

Option 3 or Option 4.

Step-by-step explanation:

I have this doubt because actually, a rhombus with a right angle (one) is not necessarily a square. Some rhombuses have one right angle and are still not squares. Now, if the four angles are right, it is a square, but this only says one.

On other hand, a parallelogram with congruent diagonals isn't a square necessarily either. Rectangles have congruent diagonals and are parallelograms.

In case you only can answer with one, I'll say is option 3, hope it helps!
