Answer:
Step-by-step explanation:
-The sine of an angle in a right triangle is given as:
-From this Trigonometric ratio, we calculate the length of the adjacent as:
We then calculate tan ∠C
Answer:
4/3
Step-by-step explanation:
The right triangle is a 3-4-5 triangle- the opposite side of a is 3 (based on 3/5 which is opp/hyp) and the hypnotuse is 5. The ohter side is 4 no matter how it is solved individually. For tan, it is opp/adj so the opp of angle c is 4 and the adj is 3. Therefore it is 4/3. :D The other person flipped it.
x - the shortest side
2x
x + 28
The sum of these must be equal to the perimeter of the flower bed, so
x + 2x + x + 28 = 184
4 x + 28 = 184 Combined like terms
4x = 156 Subtracted 28 from both sides
x = 39 Divided both sides by 4.
So the dimensions are 39 feet, 78 feet, and 67 feet
Answer:
18,375
Step-by-step explanation:
Perimeter = 126 cm, area = 972 cm2
Perimeter = 46 cm, area = 972 cm2
Perimeter = 126 cm, area = 131.25 cm2
Perimeter = 46 cm, area = 131.25 cm2
Perimeter = 126 cm, area = 972 cm2
Perimeter = 46 cm, area = 972 cm2
Perimeter = 126 cm, area = 131.25 cm2
Answer:
Perimeter = 126 cm, area = 972 cm2
Step-by-step explanation:
Rectangle perimeter:
Rectangle area:
When scaled, the perimeter will change by same factor but the area by the square of same factor.
Applying to the given rectangle
Perimeter:
Area:
Correct choice is B
Answer:
Perimeter = 126cm
Area = 972cm^2
Step-by-step explanation:
6*4.5 = 27
8*4.5 = 36
Perimeter = 27*2+36*2= 126 cm
Area = 27*36 = 972 cm^2

2.8y + 6 + 0.2y = 5y – 14
Answer:
Step-by-step explanation:
Simplifying
2.8y + 6 + 0.2y = 5y + -14
Reorder the terms:
6 + 2.8y + 0.2y = 5y + -14
Combine like terms: 2.8y + 0.2y = 3y
6 + 3y = 5y + -14
Reorder the terms:
6 + 3y = -14 + 5y
Solving
6 + 3y = -14 + 5y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-5y' to each side of the equation.
6 + 3y + -5y = -14 + 5y + -5y
Combine like terms: 3y + -5y = -2y
6 + -2y = -14 + 5y + -5y
Combine like terms: 5y + -5y = 0
6 + -2y = -14 + 0
6 + -2y = -14
Add '-6' to each side of the equation.
6 + -6 + -2y = -14 + -6
Combine like terms: 6 + -6 = 0
0 + -2y = -14 + -6
-2y = -14 + -6
Combine like terms: -14 + -6 = -20
-2y = -20
Divide each side by '-2'.
y = 10
Simplifying
y = 10
Answer:
y= 11
Step-by-step explanation:
we have:
2.8y + 6 + 0.2y = 5y – 14
or 3y + 6 = 5y -14
and 3y + 6 - 6 = 5y -16 -6
and 3y = 5y -22
and 3y - 5y = -5y +5y -22
so -2y = -22
finally y = -22/-2
or y=11
Hope that useful for you.
