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!!

Two friends are collecting stuffed animals. Veronica has 5 more than double the number of stutted
STatiana [176]

v + m = 32 and v = 5 + 2m are the equations that are used  to determine m, the number of stuffed animals Mariposa has

Number of stuffed animals Mariposa has is 9 and number of stuffed animals with Veronica is 23

<h3><u>Solution:</u></h3>

Let "v" be the number of stuffed animals with Veronica

Let "m" be the number of stuffed animals with Mariposa

Given that,

Together, they have 32 stuffed animals

Therefore,

v + m = 32  --------- eqn 1

Veronica has 5 more than double the number of stutted  animals as her friend Mariposa

Therefore,

Number of stuffed animals with Veronica = 5 + 2(number of stuffed animals with Mariposa)

v = 5 + 2m ---------- eqn 2

Thus eqn 1 and eqn 2 can be used to determine m, the number of stuffed animals Mariposa has

Let us solve eqn 1 and eqn 2

Substitute eqn 2 in eqn 1

5 + 2m + m = 32

5 + 3m = 32

3m = 32 - 5

3m = 27

<h3>m = 9</h3>

Substitute m = 9 in eqn 2

v = 5 + 2(9)

v = 5 + 18

<h3>v = 23</h3>

Thus number of stuffed animals Mariposa has is 9 and number of stuffed animals with Veronica is 23
