answer:

measure of angle 1 is 130°.

step by step:

angle 8 = 50

angle 6 = 50 (because of vertical angles)

angle 4 = 50 (because fo alternate interior angles)

therefore, angle 1 = 130 (because of linear pairs)

angle 1 and angle 4 add up to 180°

F(r) = 3.14r2 . What is f(3)?

lbvjy [14]

Answer:

The value of f(3) = 28.26

Step-by-step explanation:

You have to do is to substitute r = 3 into the function :

$f(r) = 3.14 \times {r}^{2}$

$f(3) = 3.14 \times {3}^{2}$

$f(3) = 3.14 \times 9$

$f(3) = 28.26$

Determine if DE is parallel to AC. Show all your work!!!

skelet666 [1.2K]

Answer:

Step-by-step explanation:

We will prove the converse of the postulate,

"If a line parallel to one side of a triangle and it intersects other two sides of the triangle, then the line will divide both the sides in the same ratio"

Segment DE intersects AB and BC at D and E respectively,

Ratio of the segments of two sides,

$\frac{AD}{DB}=\frac{CE}{EB}$

$\frac{22.5}{15}=\frac{24}{40-24}$

1.5 = 1.5

True.

Therefore, lines AC and DE are parallel.
