Answer:
Step-by-step explanation:
CD = 4sin30 = 4(1/2) = 2
∠BDC = 180 - 90 - 60 = 30°
BDcos30 = CD = 2
BD = 2/cos30 = 2/ (½√3) = 4/√3 = (4/3)√3
another way to do it would be
∠BDC = 180 - 90 - 60 = 30°
∠ADC = 180 - 90 - 30 = 60°
therefore
∠BDA = 60 - 30 = 30°
We can see the upper triangle is an isosceles triangle where lengths AB = BD and the angle between them is 180 - 30 - 30 = 120°
Using law of Sines
4/sin120 = BD/sin30
BD = 4sin30/sin120 = 4(½)/(½√3) = 4/√3 = (4/3)√3
or we could use the law of Cosines
c² = a² + b² - 2abcosC
BD² = AB² + 4² - 2(AB)(4)cos30
BD = AB = x
x² = x² + 4² - 2(x)(4)cos30
0 = 4² - 2(x)(4)cos30
4² = 2(x)(4)cos30
x = 4²/(2(4cos30)) = 2/cos30 = 2/ (½√3) = 4/√3 = (4/3)√3

Answers
Answer:
Hope this helps.
Step-by-step explanation:
When measuring for floor tile the rule is:
Length x Width + Waste = Amount Needed
Waste Factor will vary based upon tile size, layout, configuration of room, patterns, etc. Typical waste factor is about 10%. Add 15% for tile being installed diagonally or for a room with lots of jogs and corners. These installations will require more cuts and thus more waste.

1. find measure of A.
2. find measure of B.
3. find measure of C
4. find measure of D
pls give picture and explanation
Answers
Answer:
Measure of angle A = 120°
Measure of angle B = 98°
Measure of angle C = 104°
Measure of angle D = 140°
Step-by-step explanation:
Find measure angle A :-Since the two straight lines are parallel
, then A + 12X =180° (alternate angles)
, then A = 180° - 12X
Since the two straight lines are parallel
, then measure angle A = measure angle (25X-5)°
(opposite angles)
, then 180° - 12X = 25X - 5° (solve it like a normal equation)
, then 180° + 5° = 25X + 12X
, then 185° = 37X
, then X = 185° ÷ 37
= 5
, then measure of angle A = 180° - ( 12 x 5 )
= 180° - 60°
, then measure angle A = 120°
Find measure angle B :-Since the two straight lines are parallel
, then measure angle B = measure angle 14X (corresponding angles)
, then 15X - 7 = 14X
, then 15X - 14X = 7
, then X = 7
Since X =7
, then measure angle B = (15 x 7) - 7
= 105° - 7
, then measure angle B = 98°
Find measure angle C :-Since the two straight lines are parallel
, then measure angle C = 8X
(opposite angles)
, then 5X + 39 = 8X
, 39 = 8X - 5X
, 39 = 3X
, then X = 39 ÷ 3
, X = 13
Since X = 13
, then measure angle C = (5 x 13) +39
= 65 + 39
, then measure angle C = 104°
Find measure angle D :-Since straight that angle D lies on = 180°
, then sum of measure of and D and 4X =
180°
, then (12X + 20) + 4X = 180°
, then 16X + 20 = 180°
, then 16X = 160° (resulting from 180° - 20°)
, then X = 10
Since X = 10
, then 12 x 10 + 20 = 120 + 20
,the measure angle D = 140°

Answers
Answer:
B is the correct answer. I just took the test :))
Step-by-step explanation:
Option B is correct, Divide R₂ by 2 and R₃ by 3 is the next step in solving this augmented matrix using the Gauss-Jordan elimination method.
In the Gauss-Jordan elimination method, the goal is to transform the augmented matrix into row-echelon form and then into reduced row-echelon form to solve the system of linear equations.
To achieve this, we perform row operations on the matrix.
In the given augmented matrix:
[tex]\left[\begin{array}{ccc}1&0&0\\0&2&0\\0&0&3\end{array}\right] .\left[\begin{array}{c}5&8&9\end{array}\right][/tex]
We can divide R₂ (Row 2) by 2 and R₃ (Row 3) by 3 to simplify the matrix further we do this to make the leading coefficient (the number at the leftmost position in each row) of each row equal to 1, which is a requirement for row-echelon form.
After dividing R₂ by 2 and R₃ by 3, the augmented matrix becomes:
[tex]\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right] .\left[\begin{array}{c}5&4&3\end{array}\right][/tex]
