Answer:

JK = 24

Step-by-step explanation:

Δ BKJ and Δ BCA are similar and ratios of corresponding sides are equal, that is

\frac{JK}{AC} = \frac{BK}{BC} , substitute values

\frac{JK}{40} = \frac{3}{5} ( cross- multiply )

5JK = 120 ( divide both sides by 5 )

JK = 24

Answer it and show your work. Which letter choice is it.
ivanzaharov [21]

Answer:

b = 55 degrees

Step-by-step explanation:

The angles 30, a, b and 45 must sum up to 180 degrees

Subtracting (30 + 45) from both sides leaves us with a + b = 105 degrees.

But b = a + 5.  Substituting a + 5 in the equation above yields

a + a + 5 = 105 degrees, so that

2a = 100 degrees, and a = 50 degrees.  Then b = a + 5, or b = 55 degrees.
