To find the total cost including the tax rate, we multiply by:

So in this case we have to multiply by

Therefore the price including tax is

Hence, $317.99

Find BC: triangle is laying on it's side with the point to the right point(A).
B to C= 61 degrees
C to A= 23 cm
A to B= 12 degrees
--------------------
If I interpret this correctly:
Angle A = 61º
Angle C = 12º
--> B = 103º
-------------
Side b = 23 cm
--------------
BC is side a, opposite angle A
--------------
23/sin(103) = a/sin(61)
a = 23*sin(61)/sin(103)
a =~ 20.6 cm
Hope this helped :)</span>
Answer:
Therefore
m Angle 1 = m Angle 2 = 31° ...Justified
Step-by-step explanation:
Given:
m angle 1 = ( 3x + 10 )°
m angle 2 = ( 5x - 4 )°
To Find:
m∠1 = ?
m∠2 = ?
Solution:
Vertical Angles:
The angles opposite each other when two lines cross. They are always equal.
∴ m Angle 1 = m Angle 2
Substituting the given values we get

Substituting ' x ' in Angle 1 and Angle 2 we get
m Angle 1 = 3 × 7 + 10 = 31°
m Angle 2 = 5 × 7 - 4 = 31°
Therefore
m Angle 1 = m Angle 2 = 31° ...Justified
Answer:
3 : 1
Step-by-step explanation:
Given that :
Total Marbles in bag = 44
Color of marbles in bag : red, green
Number of red marbles = 11
The ratio of green to red marbles :
Number of green marbles :
(Total marbles in bag - number of red marbles)
(44 - 11) = 33 green marbles
Hence, ratio of green to red Marbles:
Number of green marbles : number of red marbles
33 : 11
3 : 1
