If the angles of a traingle are in the ratio 2:3:4 , Find Them​

Mathematics
1 answer:
DedPeter [7]3 years ago
8 0

Answer:

40°, 60°, and 80°

Step-by-step explanation:

We know that the sum of the angles of a triangle is equal to 180°.

We can use this equation to solve for these angles:

180 = 2x + 3x + 4x

180 = 9x

20 = x

Then substitute the solution in for x to solve for the angles:

2(20) = 40°

3(20) = 60°

4(20) = 80°

Therefore, the angles are 40°, 60°, and 80°.

What is the simple interest on $360 borrowed for 30 months at 12.3%
Alex_Xolod [135]
Keeping in mind that there are 12 months in a year, therefore, 30 months is really 30/12 years,

\bf ~~~~~~ \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$360\\
r=rate\to 12.3\%\to \frac{12.3}{100}\to &0.123\\
t=years\to \frac{30}{12}\to &\frac{15}{6}
\end{cases}
\\\\\\
I=(360)(0.123)\left( \frac{15}{6} \right)\implies I=110.7

Solve for A ? <br><br> Anyone willing to help me :)
GrogVix [38]

Answer:

<h2>2.2</h2>

Step-by-step explanation:

Use the cosine law:

BC^2=AB^2+AC^2-2(AB)(AC)\cos(\angle A)

We have:

BC=a\\\\AB=4\\\\AC=3\\\\m\angle A=32^o\to\cos32^o\approx0.848

Substitute:

a^2=4^2+3^2-2(4)(3)(0.848)\\\\a^2=16+9-20.352\\\\a^2=4.648\to a=\sqrt{4.648}\\\\a\approx2.2
