Given right triangle QRS, what is the value of sin(30°)? StartFraction StartRoot 3 EndRoot Over 3 EndFraction One-half StartFrac

baherus [9]

Answer:

Option 2: $\sin(30)=\frac{1}{2}$

Step-by-step explanation:

Given:

From the triangle shown below;

A triangle QRS with angle QRS = 90°, ∠QSR = 30°.

Side QR = 5, SQ = 10 and RS = 5√3

Now, we know from trigonometric ratio that,

$\sin (A) = \frac{Opposite\ side}{Hypotenuse}$

Here, opposite side of angle QSR is QR and Hypotenuse is the side opposite angle QRS which is SQ. Therefore,

$\sin(\angle QSR)=\dfrac{QR}{SQ}\\\\\\\sin(30)=\dfrac{5}{10}\\\\\\\sin(30)=\dfrac{5}{2\times 5}=\dfrac{1}{2}$

Therefore, the value of sine of 30° is one-half. So, second option is correct.

What is the slope of the line that passes through the points (5, -10) and (11,−12)? Write your answer in simplest form.

MA_775_DIABLO [31]

Answer:

$slope=-\frac{1}{3}$

Step-by-step explanation:

Use the slope formula for two points:

$\frac{y(2)-y(1)}{x(2)-x(1)}=\frac{rise}{run}$

Insert values

$\frac{-12-(-10)}{11-5}$

Simplify

$\frac{-12+10}{11-5} \\\\\\\frac{-2}{6} \\\\-\frac{2}{6}$

Simplify

$-\frac{1}{3}$

Please help me solve this

alexandr1967 [171]

Answer:

20.5

Step-by-step explanation:

By the Triangle Midsegment Theorem, the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side. Therefore, (1/2)FH ≡ IH, (1/2)HG ≡ HJ. Knowing that IJ = 8 gives you the presidence to solve for the perimeter.
