Answer:

B. 80°

Step-by-step explanation:

The triangle in the middle has angles that:

Supplementary with 110°
Supplementary with 150°
Same with x, as alternate exterior angles are congruent

Interior angles of a triangle sum to 180°

Find x:

x + (180° - 110°) + (180° - 150°) = 180°
x + 70° + 30° = 180°
x + 100° = 180°
x = 80°

Correct choice is B

Janet has three coins.

tatyana61 [14]

Answer:

Janet has coins worth 252.5, 101, and 50.5.

Step-by-step explanation:

Let us call the three coins $a,b$ , and $c$ .

The first coin $a$ is 5 times another coin (let's say $b$ ); therefore,

$a = 5b$ ,

and the third coin is 2 times the value of another coin (it's coin $b$ ):

$c =2b$ .

The total worth of all coins is 404; therefore,

$a+b+c =404$

$5b+b+2b =404$

$8b =404$

$\boxed{b = 50.5}$

with the value of $b$ in hand, we find $a$ and $c$ :

$a = 5b = 5(50.5)$

$\boxed{a = 252.5}$

and for $c:$

$c = 2 b = 2 (50.5)$

$\boxed{c = 101}$

Thus, Janet has 3 coins worth 252.5, 101, and 50.5.
