Answer:

Step-by-step explanation:

Angles 3, 4, and 5 are supplementary to each other, meaning that all of them added together equal 180. Therefore, to solve for x:

x + 18 + x + 15 + 4x + 3 = 180 and

6x + 36 = 180 and

6x = 144 so

x = 24

Angles 1 and 3 are vertical angles, so they are congruent, meaning they both have the exact same angle measure. If angle 3 measures, x + 18, so does angle 1. If x = 24, then angle 1 = 24 + 18 which is 42 degrees.

That also answered part c. Angles 1 and 3 are not complementary, they are vertical.

r-ruslan [8.4K]

Answer:

Juan believes the answer is -2/15.

Step-by-step explanation:

The given problem is :

$\dfrac{-1}{3}\times \dfrac{2}{5}$

We need to solve the problem.

$\dfrac{-1}{3}\times \dfrac{2}{5}=\dfrac{-1\times 2}{3\times 5}\\\\=\dfrac{-2}{15}$

So, the answer to the problem is $\dfrac{-2}{15}$ . Hence, Juan is correct.
