Angle A and angle B are complementary angles. If m∡a = 4x and m∡b = 3x +13, what is the measure of the smaller angle?

bagirrra123 [75]

Answer:

Step-by-step explanation:

Complementary angles mean two two angles sum with equal 90 degrees. Therefore you would need to create an equation to solve for the value of x.

4x+3x+13=90

-13 -13

7x=77

/7 /7

X=11

Now plug in the value of x.

A=4(11) B=3(11)+13

A=44. B=33+13

B=46

Angle a is the smaller angle and measures at 44°

What is the equation of the following line? Be sure to scroll down first to see

Rom4ik [11]

<h2>Answer:</h2>

-1/3x

<h2>Step-by-step explanation:</h2><h3>Known :</h3>

x1 = -3
x2 = 0
y1 = 1
y2 = 0

<h3>Asked :</h3>

Correct line equation

<h3>Solution :</h3>

We can find the straight line equation using this formula,

$\frac{y-y1}{y2-y1} = \frac{x-x1}{x2-x1}$

Insert all we know inside the formula,

$\frac{y-1}{0-1} = \frac{x-(-3)}{0-(-3)}\\\frac{y-1}{-1} = \frac{x +3}{3}\\$

Use cross multiplication,

3(y - 1) = -1(x + 3)\

3y - 3 = -x - 3

3y = -x - 3 + 3

3y = -x

y = -1/3x

<h3>Conclusion :</h3>

The correct equation is y = -1/3x

What integer is equivalent to 9^3/2

Shalnov [3]

$9^{\frac{3}{2}}$ is equivalent to: $\sqrt{9^{3}}$
$\sqrt{9^{3}}$
$=9 \cdot \sqrt{9}$
$=9 \cdot 3 = 27$

Hence, $9^{\frac{3}{2}} = 27$
