I know this is like the 700th question I've asked​

Mathematics
1 answer:
AysviL [449]3 years ago
6 0

Answer:

BC = 15

Step-by-step explanation:

Because of parallel lines, AD and BE, triangles ADC and BEC are similar.

In similar triangles, the lengths of corresponding sides are proportional.

AC/BC = DC/EC

We see that AC = AB + BC = 3 + BC

Also, DC = DE + EC = 2 + 10 = 12

(3 + BC)/BC = 12/10

(3 + BC)/BC = 6/5

Cross multiply.

5(3 + BC) = 6BC

15 + 5BC = 6BC

15 = BC

BC = 15

Whenever you are graphing an inequality,

< or > means the line is dotted
≤ or ≥ means the line is full and complete

The equation is x ≤ 3 so the answer is either A or B


x ≤ 3 means that x is less than or equal to 3, so the part that is shaded blue is supposed to be 3 and below.

The answer is A

△ABC has a&gt;b&gt;c. If one of the angles in the triangle is 60°, name the angle that can be equal to 90°.
Aleksandr-060686 [28]

Answer:

Angle A

Step-by-step explanation:

a is greater than b, which is greater than c

a triangle has 180 degrees

so 180-90 is 90

90-60 is 30

a>b>c

90>60>30

this would be a right triangle since one of the angles is 90 degrees
