What is the length of segment DC?

Mathematics
1 answer:
erik [133]3 years ago
5 0
Since BD is the bisector of angle B, the segments to its left are proportional to those to its right. The proportion can be written at least 4 ways, but it is convenient to write it with x in a numerator.

x/(15 cm) = (5.6 cm)/(7 cm)
Multiplying by 15 cm, we get
x = (15 cm)×(5.6/7) = 12 cm

The appropriate choice is
  D. 12 cm

Points A B C D and E are collinear and in that order. Find AC if AE=x+50 and CE=x+32
Lana71 [14]

Answer:

18

Step-by-step explanation:

Points A B C D and E are collinear.

\therefore AE = AC + CE\\\therefore AC = AE - CE\\\therefore AC = x + 50 - (x + 32) \\\therefore AC = x + 50 - x - 32 \\\therefore AC =  50 - 32 \\ \huge \red{ \boxed{\therefore AC = 18}}

The bases in a major league diamond are locate at the corners of a 900 yd^2 square as pictures below. a player throws a baseball
Licemer1 [7]
To answer this, you will use the area of 900 square yards to determine the distances between the bases.  Each side of the square is 30 yards, so it will be 30 yards from 1st to home and from 1st to 2nd.  

The distance from home to 2nd is a diagonal in the square (the hypotenuse).

You will use the Pythagorean Theorem to find this distance.

a^2 + b^2 = c^2
30^2 + 30 ^2 = c^2
900 + 900 + c^2
1800 = c^2

The square root of 1800 is approximately 42.4 yards.

The ball travels approximately 42.4 yards.
