Answer:
x=56
Step-by-step explanation:
I may be wrong but
That’s a pentagon so
5-2=3
180x3=540 ( total area of a pentagon)
89+99+72= 260
540-260=280
3+2=5
280/5=56
x=56
(7+21)=28
28(3-I)=
28•3 =84
28•I=28i
28/84=3,5
3,5=I
30 miles for a single gallon.
first we find out how many gallons would be used.
number of gallons = 1020/30
gallons = 34.
and since 1 gallon costs $4.06
34 gallons would cost = 34 x 4.06 = $138.04
Answer:
162
Step-by-step explanation:
Divide 216 by 4
Then multiply 3 times
That's the answer
Answer:
Step-by-step explanation:
Given triangle ABC is a right triangle.
m∠ACB = 60°
m∠CAB = 30°
m(AC) = 1 unit
A). Shorter side of the given triangle = Side BC
By applying cosine rule,
cos(∠C) = 
cos(60°) = 
BC = 
BC = 
Length of the shorter side = 0.5 units
B). Longer side of the given triangle = side AB
By applying Pythagoras theorem in the given triangle,
AC² = AB² + BC²
1² = AB² + 
1 = AB² + 
AB = 
AB = 
AB = 
Length of the longer side =
