Answer:
12.11 gallons
Step-by-step explanation:
Ciara's car used gas on 160 mile road trip = gallons
= gallons
Ciara's car used gas on 1 mile road trip =
=
= gallons
Ciara expect to use on a 250 mile road trip =
=
=
≈ 12.11 gallons
Ciara should expect to use or 12.11 gallons of gas.
Perimeter of ∆ABC = 25
Difference between the two sides is 4
Find: AB, BC, AC
List the sides of ΔRST in in ascending order (shortest to longest) if:
m∠R = 3x+42°, m∠S = 4x−11°, and m∠T = x+13°
List the sides of ΔRST in in ascending order (shortest to longest) if:
m∠R = 2x+11°, m∠S = 3x+23°, and m∠T = x+42°
Answer with Step-by-step explanation:
1.In triangle ABC
AB=BC
Let AB=BC=x and AC=y
Perimeter of triangle ABC=25
...(1)
...(2)
Adding equation (1) and (2)
Substitute x=9.67 in equation (2)
2.
By using triangle angle sum property
Substitute the values then we get
Substitute the value
(Side ST is opposite to angle R, Side RT is opposite to angle S
(side RS is opposite to angle T)
When a>b
Then , opposite side of a> opposite side of b
RS<RT<ST
3.
By using triangle angle sum property
Substitute the values then we get
Substitute the value
RT>RS
RS>ST
ST<RS<RT
b. sin x
c. -cot x
d. cot x
