It would be 8 because 3 less than 8.
Hope this helps! :D

Solve for X. Round to the nearest 10th. Need to use COS, TAN, or SIN

Brums [2.3K]

tan( 75 ) = 17 / x

3.732 = 17 / x

x = 17 / 3.732

x = 4.5551

x = 4.56

Solve the equation 3/y = 4/5

netineya [11]

Step-by-step explanation:

<u>Step 1: Cross Multiply</u>

$\frac{3}{y} = \frac{4}{5}$

$5(3) = 4(y)$

$15 = 4y$

<u>Step 2: Divide both sides by 4</u>

$15 / 4 = 4y / 4$

$3.75 = y$

Answer: $y = 3.75$

Find the function value, if possible. (If an answer is undefined, enter UNDEFINED.)

ddd [48]

Answer:

f(x + 2) = 3x + 2

Step-by-step explanation:

Simply replace wherever you find x in the function f(x) with (x + 2), like so:

f(x + 2) = 3(x + 2) - 4

f(x + 2) = 3x + 6 - 4

f(x + 2) = 3x + 2

Can somebody help me, please?

Sveta_85 [38]

Answer:

a. $x=10 \textdegree$

$m\angle L=39\textdegree\\\\m\angle M=51\textdegree\\\\m\angle K=90\textdegree$

Step-by-step explanation:

a. We know that angles in a triangle add up to 180°.

-The right angle triangle in the right triangle has a measure of 90°.

We can therefore equate our angles to 180° and solve for x;

$180=\perp\angle+(2x+19)+(3x+21)\\\\180=90+(2x+19)+(3x+21)\\\\90=5x+40\\\\5x=50\\\\x=10\textdegree$

Hence, the angle measure is x=10°

b. Having calculated the value of x from a above as x=10°, we can substitute to find the measures of the two acute angles:

$m\angle L=(2x+19)\textdegree\\\\=(2\times 10+19)\textdegree\\\\=39\textdegree\\\\m\angle M=(3x+21)\textdegree\\\\=(3\times 10+21)\textdegree\\\\=51\textdegree$

Since, the m∠K is a right angle, it measures 90°
