What is the measure of X?

vlabodo [156]

Answer:

The answer is B.

Step-by-step explanation:

Given that the total angles in a triangle is 180° so in order to find the value of x, you have to substract 60° and 80° from 180° :

$60 + 80 + x = 180$

$140 + x = 180$

$x = 180 - 140$

$x = 40$

Solve for the indicated variable. 8x + 4y = 12; y

Ket [755]

Answer:

$y=-2x+3$

Step-by-step explanation:

Given: $8x+4y=12$

To solve for y, let us first isolate y on one side of the equation. We can do this by subtracting $8x$ from the left and move it to the right. We then get:

$4y=12-8x$

Now, we have y isolated. We now have to remove the 4 from the y. The only way to do this is divide both sides by 4. We then get our final answer:

$y=3-2x$

We can clean this up by putting it in a common form, slope-intercept form:

$y=-2x+3$

find the missing angle and side measures of the triangle. The triangle has one angle that measures 90 degrees, and the other two

Tamiku [17]

Since we know that the measure of one of the angles is 90°, we know that we have a right triangle with legs 1 and $\sqrt{3}$ . Now lets apply the Pythagorean theorem: $hypotenuse= \sqrt{leg^{2}+leg^{2} }$ , to find our hypotenuse:
$h= \sqrt{1^{2}+ \sqrt{3}^{2} }$
$h= \sqrt{1+3}$
$h= \sqrt{4}$
$h=2$

Now that we know that the measure of the hypotenuse is 2, lets use the trig function sine to find one of the angles that we are going to call $x$ .
Remember that $sin(x)= \frac{opposite.side}{hypotenuse}$ , so:
$sin(x)= \frac{1}{2}$
$x=sin^{-1} ( \frac{1}{2} )$
$x=30$
Now that we have two angles, remember that the sum of the interior angles of a triangle is 180°; lets use that to find our final angle $y$ :
$y=180-(90+30)$
$y=180-120$
$y=60$

We can conclude that the measure of the hypotenuse of our triangle is 2, and the measure of its missing angles are 30° and 60° respectively.
