A 12-m ladder is leaning against a wall.

Mathematics
1 answer:
Len [333]2 years ago
7 0

Answer:

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle. Your best bet when learning/visualizing word problems is to draw a picture, then learn how to visualize in your head over time.

3^2+x^2=12^2\\9+x^2=144\\x=\sqrt{135}

The radical can be further simplified because 135 is the product of 9 and 15. 9 has a perfect root of 3.

x=3\sqrt{15} meters or 11.62 meters

GenaCL600 [577]

1:00 ? because it <em>says </em>that there is a needed 12 minuted between the films plus another 12 minutes of previews which equals 24.... sooo 24 plus 36 should equal 60 which is an hour so the answer as far as i know is 1:00.... Hope this helped :)

ABCD is a parallelogram. If a CDA - 57 then BCD-_?
Paha777 [63]

Answer:

57

Step-by-step explanation:

It is given in the question that length CDA = 57.

Since the shape is a parallelogram, then we know that length AD=BC and AB=CD.

CDA = CD + AD

BCD = BC + CD

Since BC=AD and CD=CD

BCD = BC + CD is the same as CD + AD = CDA

Therefore BCD is the same length as CDA = 57

In other words, CDA is made up of a long side and a short side = 57

BCD is also made up of a long side and a short side, and since the longs sides are equal to each other and the short sides are also equal to each other in a parallelogram, BCD is the same length as CDA = 57.

Hope this helped!
