Someone helpp !! I don’t understand this at all
Naddika [18.5K]

Answer:

∠AB=9

Step-by-step explanation:

<em>the pyagrothyes therom= </em>a^{2}<em>+</em>b^{2}<em>=</em>c^{2}

<em>to find ∠AB we need to find the height of the triangle.</em>

<em>replace the variables:</em>

a^{2}<em>+</em>6^{2}<em>=</em>9^{2}

<em>=</em>9^{2}<em>-</em>6^{2}<em>=</em>a^{2}

<em>simplify:</em>

<em>81-36=</em>\sqrt{45}

<em>now we solve for ∠AB</em>

<em>replace the variables:</em>

6^{2}<em>+</em>\sqrt{45}<em>=</em>c^{2}

<em>simplify:</em>

<em>36+45=</em>\sqrt{81}

\sqrt{81}<em>=9</em>

I hope this helps you!!

have a nice day!!

Can You Please Explain How To Do Problem #10? Thank you! :)​
alexandr1967 [171]

Answer:

separate and square both the top and bottom

the square of square root three is just 3 and the square of  3 (the bottom of the fraction) is 9

so now you have 3(i^2) /9

you can simplify this by three  and then i^2 is -1

you now have -1/3 and thats the final answer

Write the equation of the line which passes through (1, 2) and with slope of −1/3
Sati [7]

Answer:

<h2>          x + 3y = 7            </h2>

Step-by-step explanation:

The equation of a line which passes through <em>(x₁, y₁)</em> and with slope of <em>m</em> in point-slope form:

                                y - y₁ = m(x - x₁)

m = -¹/₃

(1, 2)    ⇒   x₁ = 1,  y₁ = 2

Therefore,  the equation of the line which passes through (1, 2) and with slope of −1/3 in point-slope form:

y - 2 = -¹/₃(x - 1)

y - 2 = -¹/₃x + ¹/₃                     {add ¹/₃x to both sides}

¹/₃x + y - 2 = ¹/₃                     {add 2 to both sides}

¹/₃x + y = 2¹/₃                       {multiply both sides by 3}

x + 3y = 7
