2 angles of a triangle are the same size. the 3rd is 3 times as large as the 1st

myrzilka [38]

Answer:

36°, 36° and 108°

Step-by-step explanation:

let the equal angles be x then the third angle = 3x

The sum of the 3 angles in a triangle = 180°, thus

x + x + 3x = 180, that is

5x = 180 ( divide both sides by 5 )

x = 36

and 3x = 3 × 36 = 108

The 3 angles are 36°, 36° and 108°

In AGHI, h = 300 inches, G=30° and H=29º. Find the length of i, to the nearest<br> inch.

dalvyx [7]

Given:

In triangle GHI, h = 300 inches, G=30° and H=29º.

To find:

The length of i.

Solution:

We have, G=30° and H=29º.

Using angle sum property, we get

$m\angle G+m\angle H+m\angle I=180^\circ$

$30^\circ+29^\circ+m\angle I=180^\circ$

$59^\circ+m\angle I=180^\circ$

$m\angle I=180^\circ-59^\circ$

$m\angle I=121^\circ$

According to Law of sines,

$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$

Using Law of sines, we get

$\dfrac{h}{\sin H}=\dfrac{i}{\sin I}$

$\dfrac{300}{\sin 29^\circ}=\dfrac{i}{\sin 121^\circ}$

$\dfrac{300}{0.4848}=\dfrac{i}{0.8572}$

Multiply both sides by 0.8572.

$\dfrac{300}{0.4848}\times 0.8572=i$

$530.44554=i$

$i\approx 530$

Therefore, the length of i is about 530 inches.

Anyone mind helping!?

Ksju [112]

Answer:

B) $3\sqrt{3}$

Step-by-step explanation:

First simplify the radical on the right.

$\sqrt{75}$ is equal to $\sqrt{25} *\sqrt{3}$ , because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.

Then we know $\sqrt{25}$ is just equal to 25, which means the simplified version of $\sqrt{75}$ is $5\sqrt{3}$ .

Then we can use this new representation to finish solving.

$8\sqrt{3}-5\sqrt{3} =3\sqrt{3}$ , so the answer would be B
