In RST, RS = 7, RT = 10, and ST = 8. Which angle of RST has the smallest measure? A T BCANNT BE DETERMINDED C R D S

Scrat [10]

Answer:

Correct answer is option A. T

Step-by-step explanation:

Given that

In a $\triangle RST$ , RS = 7, RT = 10, and ST = 8.

To find:

Smallest angle = ?

Solution:

We can use cosine rule here to find the angle.

Formula for cosine rule:

$cos B = \dfrac{a^{2}+c^{2}-b^{2}}{2ac}$

Where

a is the side opposite to $\angle A$

b is the side opposite to $\angle B$

c is the side opposite to $\angle C$

Using the cosine rule:

$cos T = \dfrac{ST^{2}+RT^{2}-RS^{2}}{2\times ST \times RT}\\\Rightarrow cos T = \dfrac{8^{2}+10^{2}-7^{2}}{2\times 8 \times 10}\\\Rightarrow cos T = \dfrac{64+100-49}{160}\\\Rightarrow cos T = \dfrac{115}{160}\\\Rightarrow \angle T = cos^{-1}(0.71875)\\\Rightarrow \angle T = 44.05^\circ$

Now, let us use Sine rule to find other angles:

$\dfrac{a}{sinA} = \dfrac{b}{sinB} = \dfrac{c}{sinC}$

$\dfrac{RS}{sinT} = \dfrac{ST}{sinR} = \dfrac{RT}{sinS}\\\Rightarrow \dfrac{7}{sin44.05} = \dfrac{8}{sinR} = \dfrac{10}{sinS}\\\Rightarrow \dfrac{7}{0.695} = \dfrac{8}{sinR} = \dfrac{10}{sinS}\\\Rightarrow sin R = \dfrac{8 \times 0.695}{7}\\\Rightarrow R = 52.58^\circ$

$\Rightarrow sin S = \dfrac{10 \times 0.695}{7}\\\Rightarrow S = 83.14^\circ$

Smallest angle is $\angle T$

Correct answer is option A. T

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: x < -2 \:\: or \:\; x >4$

____________________________________

$\large \tt Solution \: :$

$\textsf{First Inequality :}$

$\qquad \tt \rightarrow \: - 2(x + 8) + 6 > x - 4$

$\qquad \tt \rightarrow \: - 2x - 16 + 6 > x - 4$

$\qquad \tt \rightarrow \: - 2x - 10 > x - 4$

$\qquad \tt \rightarrow \: - 10 + 4 > x + 2x$

$\qquad \tt \rightarrow \: - 6 > 3x$

$\qquad \tt \rightarrow \: - \cfrac{ 6}{3} > x$

$\qquad \tt \rightarrow \: - 2 > x$

$\qquad \tt \rightarrow \: \therefore x < - 2$

$\textsf{Second Inequality :}$

$\qquad \tt \rightarrow \: - 3x + 12 < 6(x - 4)$

$\qquad \tt \rightarrow \: - 3x + 12 < 6x - 24$

$\qquad \tt \rightarrow \: 12 + 24 < 6x + 3x$

$\qquad \tt \rightarrow \: 36 < 9x$

$\qquad \tt \rightarrow \: \cfrac{36}{9} < x$

$\qquad \tt \rightarrow \: 4 < x$

$\qquad \tt \rightarrow \: \therefore x > 4$
