Answer:

m<D = 26

Step-by-step explanation:

Exterior angles thm:

83 + 6x - 4 = 21x + 4

6x + 79 = 21x + 4

6x - 21x = 4 - 79

-15x = -75

x = 5

m<D:

6x - 4

6(5) - 4

30 - 4

26

Tan9°. tan27°. tan45°. tan72°. tan81°= 1<br><br>could u plz solve it with clear process

Inga [223]

<u>Correct</u><u> </u><u>question</u><u>:</u><u>-</u>

<u>Prove </u><u>that </u><u>tan9.</u><u>t</u><u>a</u><u>n</u><u>1</u><u>7</u><u>.</u><u>t</u><u>a</u><u>n</u><u>4</u><u>5</u><u>.</u><u>t</u><u>a</u><u>n</u><u>7</u><u>3</u><u>.</u><u>t</u><u>a</u><u>n</u><u>8</u><u>1</u><u>=</u><u>1</u>

<u>LHS</u>

$\\ \sf\longmapsto tan9.tan17.tan45.tan73.tan81$

$\\ \sf\longmapsto tan9.tan81.tan17.tan73.tan45$

$\\ \sf\longmapsto tan(90-81).tan81.tan(90-73).tan73.1$

$\\ \sf\longmapsto cot81.tan81.cot73.tan73$

$\\ \sf\longmapsto 1.1$

$\\ \sf\longmapsto 1$

Solve for t. f(t)=-16t^2+576

IgorC [24]

Answer: t^2=-f-576/16

Step-by-step explanation:

Step 1. Switch the equation around:

-16t^2+576=f

Step 2. Subtract 576 from each side:

-16t^2+576-576=f-576

Step 3. Now simplify:

-16t^2=f-576

Step 4. Divide everything now by -16:

-16t^2/-16=f/-16-576/-16

Step 5. Simplify again:

t^2=-f-576/16

Hope I could help! :)

Solve for x: 6x + 1/4 (4x + 3) > 12<br> Ox><br> 10<br> 7<br> Ox> 2<br> ox= 10<br> X = 2

daser333 [38]

Given:

The inequality is:

$6x+\dfrac{1}{4}(4x+3)>12$

To find:

The values for x.

Solution:

We have,

$6x+\dfrac{1}{4}(4x+3)>12$

Using distributive property, we get

$6x+\dfrac{1}{4}(4x)+\dfrac{1}{4}(3)>12$

$6x+x+\dfrac{3}{4}>12$

$7x>12-\dfrac{3}{4}$

$7x>\dfrac{48-3}{4}$

On further simplification, we get

$7x>\dfrac{45}{4}$

Divide both sides by 7.

$x>\dfrac{45}{7\times 4}$

$x>\dfrac{45}{28}$

Therefore, the required solution is $x>\dfrac{45}{28}$ .

Note: All options are incorrect.
