Step-by-step explanation:

The solution to the matrix equation ...

  [tex]\left[\begin{array}{cc}3&-2\\6&-5\end{array}\right] \left[\begin{array}{c}x\\y\end{array}\right] =\left[\begin{array}{c}2\\-1\end{array}\right][/tex]

is shown in the attachment. It is found by multiplying the equation on the left by the inverse of the coefficient matrix.

  [tex]\left[\begin{array}{c}x\\y\end{array}\right] =\left[\begin{array}{c}4\\5\end{array}\right][/tex]

Answer:

25 inches

Step-by-step explanation:

Area is given as 75 in^2

Area of a triangle = 1/2 * base * height

             75            = 1/2 (6) * height

             75 / (1/2 * 6) = height

                     25 inches = height

Answer:

Area of the actual room = 288 m²

Step-by-step explanation:

Given:

Scale factor = 2cm to 4 m

Dimension of rectangle ball room = 6 cm and 12 cm

Find:

Area of the actual room

Computation:

Actual dimension of rectangle ball room;

⇒ [6/2]4 = 12 m

⇒ [12/2]4 = 24 m

Area of rectangle = Length x Width

⇒ Area of the actual room = Actual length x Actual width

⇒ Area of the actual room = 12 x 24

Area of the actual room = 288 m²

Answer:

EF is 109

DAB is 54.5

Step-by-step explanation:

Applying the central angle theorem, the correct statement would be:

The central angle theorem states that:

Thus:

Measure of minor arc EF = m∠ECF = 109°

m∠DAB = 1/2(109°) [m∠ECF = m∠BAD = 109°]

m∠DAB = 54.5°

Therefore, applying the central angle theorem, the correct statement would be:

Answer:

A. 18

Step-by-step explanation:

Sum of the measures of all the angles of a quadrilateral is 360°

Therefore,

[tex]2m \degree + 8m \degree + 6m \degree + 4m \degree = 360 \degree \\ 20m \degree = 360 \degree \\ 20m = 360 \\ m = \frac{360}{20} \\ m = 18[/tex]

Answer:

Step-by-step explanation:

Some useful relations are ...

  A triangle inscribed in a semicircle is a right triangle.

  Acute angles in a right triangle are complementary.

  An inscribed angle is half the measure of the arc it intercepts.

  The sum of arcs around a circle is 360°; 180° around a semicircle.

__

1. Arc DF is twice the marked inscribed angle, so is 126°. Arc FE is supplementary to that, so is ...

  arc FE = 180° -126°

  arc FE = 54°

Alternate solution: arc FE is twice angle D, which is the complement of 63°.

  2(90° -63°) = 2(27°) = 54° = arc FE

__

2. Arc GJ = 360°-68° -31° -115° = 146°

  angle GHJ = angle GIJ = 146°/2 = 73°

__

3. arc UT = 2(90° -43°) = 94°

  9x -14 = 94

  9x = 108 . . . . . add 14

  x = 12 . . . . . . . . divide by 9

Answer:

m<H = 62°

Step-by-step explanation:

If FG is congruent to HF, it means their opposite angles are also congruent to each other. This implies that, <H = <G. Thus, ∆FGH is an isosceles triangle with base angles <F and <G.

Given that m<F = 56°, therefore:

56° + 2(m<H) = 180° (sum of triangle)

2(m<H) = 180° - 56°

2(m<H) = 124°

m<H = 124/2

m<H = 62°

Answer:

y = 4

Step-by-step explanation:

Given that,

RS= 4y+2, ST = 3y+8, and RT = 38

We need to find the value of y.

As,

RT = RS+ST

Put all the values,

38 = 4y+2+3y+8

38-2-8 = 4y+3y

28 = 7y

y = 4

So, the value of y is equal to 4.
