Answer:
x = 45
Step-by-step explanation:
The 3 angles of a triangle add up to 180
<a + <b + <c = 180
substitute what you know
55+ 80 + <c = 180
combine like terms
135 + <c = 180
subtract 135 from each side
<c = 180 -135
<c = 45
x = 45
Answer:
Discount rate=33%
Step-by-step explanation:
Step 1
Determine the discounted amount as shown;
A=I-F
where;
A=discounted amount
I=initial price/original price
F=final price after discount
In our case;
A=unknown
I=$75
F=$50
replacing;
A=(75-50)=25
The discounted amount=$25
Step 2
Determine the discount rate using the formula;
Discount rate=(discount amount/original amount)×100
Discount rate=(25/75)×100=33.33%
Discount rate=33%
