Lines <em>a</em> and <em>b</em> are parallel, so lines <em>p</em>, <em>q</em>, and <em>t</em> are considered to be transversals. To solve this, you make use of the fact that alternate interior angles are equal, as are alternate exterior angles, as are corresponding angles. Of course any linear pair of angles is supplementary.

∠1 = 90° — corresponding angle to the right angle above it

∠2 = 68° — the sum of 22° and angles 1 and 2 is 180°

∠3 = 112° — supplementary to angle 2 (and the sum of 22° and 90°, opposite interior angles of the triangle)

∠4 = 112° — equal to angle 3

∠5 = 68° — equal to angle 2; supplementary to angle 4

∠6 = 56° — base angle of isosceles triangle with 68° at the apex; the complement of half that apex angle

∠7 = 124° — supplementary to the other base angle, which is equal to angle 6; also the sum of angles 5 and 6

∠8 = 124° — alternate interior angle with angle 7, hence its equal.

If each can costs $23.97 plus 6% tax, what is the total cost? Round to two decimal places.
kap26 [50]
The total cost for one can is: $25.41.
__________________________________________________
Let us assume that we want to know the total cost of ONE CAN.
_____________________________________________
To calculate our answer:
_______________________________
$ 23.97 + [ (6/100) * 23.97)] = Our answer, in dollars.
__________________________________________
Note: "6%" = 6/100 = 0.06
_______________________
Rewrite as:
____________
$ 23.97 + [ (6/100) * 23.97)]  = our answer, in dollars; 
_____________________________________________
    $ 23.97 + (0.06 * 23.97)

            =    $ 23.97 + 1.4382

            =      $ 25.4082 ; Round to decimal places, to get:
                                         <span>→ $ 25.41

What is the Y-Intercept?
antoniya [11.8K]

Answer: The y-intercept is 1

Step-by-step explanation:

On a graph, the y-intercept is the point where the line intersects the y-axis. The corresponding x-coordinate is always 0. ... When a linear equation is written in slope-intercept form (y=mx+b), the slope is represented by the variable m. It is the coefficient to x in the equation.

HELP ME PLZZZZ!!!!!<br><br><br> It’s just 21 and 22
galina1969 [7]

Answer:

21) 12 cm

22) 5.9 cm

Step-by-step explanation:

21) The base is 10, and if the other two sides are congruent and the perimeter is 36, we can figure out with simple algebra that the sides are 13 cm long.

Half of 10 is 5, so we can use the pythagorean theorem.

5^2+x^2=13^2

Rearranging the variables we have 169-25=x^2

144=x^2

x can be plus or minus 12, but since negative length is impossible we find that x is positive 12 cm.

22) We want to use sine, because we have opposite and hypotenuse. A simple and easy way to memorize this is the SohCahToa method. If we have opposite (O) and hypotenuse (H) we have OH. Soh has the letters O and H, and the S means we should use sine.

sine 36=a/10

Plug this into a calculator or desmos scientific calculator to get a=5.9
