Answer:
x=25°, y=10°
Step-by-step explanation:
∠A+∠B=180°
8y+10y=180°
18y=180°
y=10°
∠B+∠C=180°
10y+4x-20°=180°
10*10°+4x=180°+20° (y=10°)
100°+4x=200°
4x=200°-100°
4x=100°
x=25°
Answer:
-2
Step-by-step explanation:
use the slope formula which is y2-21/x2-x1
these are what i chose my numbers to be
-4=x1
-1= y1
-2= x2
-5= y2
-5-(-1)/-2-(-4) = -2
thats all
Answer:
5
Step-by-step explanation:
Verticle angles are the angles opposite of each side.
Let the total cost of the item be represented by C and the price be represented by P, then given that t<span>he total cost of an item including sales tax is directly proportional to its price, thus</span>

where k is a constant.
Given that <span>the total cost of a $32 item is $33.60, thus

Therefore, the total cost on a $55 item is given by
