Answer:

10 cm

Step-by-step explanation:

we know that the perimeter of a rectangle= 2(l+w)

given that the perimeter is 46 cm and length is 13 cm, so by putting the values we get,

2(13+w)=46

= 26+2w=46 (opening the brackets)

= 2w= 46-26

= 2w=20

= w=20/2

w= 10 cm

Cheers.

A point in the figure is selected at random. Find the probability that the point will be in the shaded region.

lesya [120]

Area of the figure:
Af = a² + 2 a²/4 π = 2.57 a²
Area of the shaded region:
As = 2 a²/4 π = 1.57 a²
x = (1.57 · 100) / 2.57 = 61 % ≈ 60 %
Answer: B) about 60 %

The Red Line in the figure is an altitude of triangle hjl. Using right angle trig and properties of equality, y sin L = x = z si

aivan3 [116]

Answer:

$\Large \boxed{\mathrm{\bold{C}}}$

Step-by-step explanation:

$\sf \displaystyle sin(\theta) =\frac{opposite}{hypotenuse }$

$\sf \displaystyle sin(L) =\frac{x}{y}$

$\sf \displaystyle sin(H) =\frac{x}{z}$

$\displaystyle \sf \frac{sinL}{z} =\frac{sinH }{y}$

$\displaystyle \sf \frac{\frac{x}{y} }{z} =\frac{\frac{x}{z} }{y}$

Simplifying the expression.

$\sf \displaystyle \frac{x}{yz } = \frac{x}{yz} \ (true)$

$\displaystyle \sf \frac{z}{sinL} =\frac{y}{sinH}$

$\displaystyle \sf \frac{z}{\frac{x}{y}} =\frac{y}{\frac{x}{z}}$

Multiplying both sides by x.

$\sf yz=yz \ (true)$
