In the diagram below, abc - dec. what is the value of x?
a 5
b. 3
c. 6
d. 4

C

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

= , substituting values

= ( cross- multiply )

21x = 7(24 - x) ← distribute

21x = 168 - 7x ( add 7x to both sides )

28x = 168 ( divide both sides by 28 )

x = 6 → C

there is no

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
