Answer:

m∠CAD = 49degrees

Step-by-step explanation:

For a rectangle ABCD if m∠BAC=4x+5and m∠ACD=5x−4, then;

m∠BAC = m∠ACD (alternate angles)

4x+5 = 5x - 4

4x-5x  = -4-5

-x = -9

x = 9

Also

m∠BAC+m∠CAD = 90

4x+5+m∠CAD = 90

4(9)+5+m∠CAD = 90

36+5+m∠CAD = 90

41+m∠CAD = 90

m∠CAD = 90-41

m∠CAD = 49degrees

Convert the following to standard form <br><br>y=2/5 x - 1/3​
Afina-wow [57]

<u>Given </u><u>:</u><u>-</u>

  • y = 2/5x - 1/3

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • To convert the given equation into standard form.

<u>Solution</u><u> </u><u>:</u><u>-</u>

As we know that the standard form of the line is ,

\sf\longrightarrow ax + by + c = 0

So the given equation is ,

\sf\longrightarrow y = 2/5x -1/3

\sf\longrightarrow y = 6x - 5/15

\sf\longrightarrow 15y = 6x - 5

\sf\longrightarrow 6x -15y -5 = 0

<u>Hence</u><u> the</u><u> required</u><u> </u><u>equation</u><u> of</u><u> the</u><u> line</u><u> is</u><u> </u><u>6</u><u>x</u><u> </u><u>-15y-5=</u><u>0</u><u>.</u>

Solve for the missing length and the other two angles in the triangle below
Klio2033 [76]

Answer:

AC = 3.72 units

Angles:

A = 132.6°

C = 27.4°

Step-by-step explanation:

AC² = 5² + 8² - 2(5)(8)cos(20)

AC² = 13.82459034

AC = 3.718143399

3.718143399/sin20 = 8/sinA

sinA = 0.7358944647

A = 180 - 47.38285134

A = 132.6171487

3.718143399/sin20 = 5/sinC

sinC = 0.4599340405

C = 27.38285134
