the missing angle is 
° .
<u>Step-by-step explanation:</u>
Here we have , a triangle knowing that one angle measures 63 degrees and the the other measures 48. We need to tell e what the missing angle measure must be. Let;s find out :
We know that , by the property of triangle : Sum of all the three angles of a triangle is always 180° . Let angles of triangle be a,b,c :
⇒ 
In question we have following parameters as :
Putting these value in we get :
⇒
⇒ 
⇒ 
⇒ 
⇒ °
Therefore , the missing angle is ° .
Answer:
x = 8/3 and y = 32/3
Step-by-step explanation:
Add the two equations, getting -3y = -32, thus y = 32/3
Sub for y in first equation, getting 5x + 32/3 = 24
5x = 40/3
x = 8/3
Answer: $5,60 will be taken off the price
Step-by-step explanation:
Take off = regular price·20/100
Take off = $28·20/100 = $560/100 = $5,60
Price after discount = $28 - $5.60 = $22.4
Answer: $5,60 will be taken off the price
