Answer:

<h2>By angle sum property:</h2>

BAC+ABC+BCA=180°

90°+45°+x=180°

135°+x=180°

x=45°=BCA

<h2>since BCA=ABC=<u> </u>45° each </h2><h2>therefore,</h2>

$AB=AC \\ (isosceles \: triangle \: \\ theorem)$

On a basketball court the free throw line is marked off geometrically this area of the court is called a key and is topped

Alenkinab [10]

Step-by-step explanation:

Arc length formula is

$s = rx$

where x is radinas.

A semi circle has a radian measure of

$\pi$

The radius is half of the diameter, 12 so the radius is

$12 \times \frac{1}{2} = 6$

So the arc length is

$6 \times \pi = 6\pi$

Area of semi circle is

$\frac{1}{2} \pi {r}^{2}$

where r is the radius.

$\frac{1}{2} \pi6 {}^{2}$

$\frac{1}{2} 36\pi$

$18\pi$

A dialation produces a shape that is the same shape but different size. so we draw a new triangle about point B where A'B=2AB
so B and B' are the same and
AB and BC will be parts of the sides. and A' is located on the ray

Matt started doing extra chores around the house and his allowance changed from $30 per week to $40 per week. What is the percen

slega [8]

Answer:

33.3%

Step-by-step explanation:

Let's say the percent change is x%. Then the equation is:

30 + x% * 30 = 40

Subtract 30 from both sides:

x% * 30 = 10

Divide by 30:

x% = 10/30 = 1/3

Remember that % simply means "out of 100", so:

x/100 = 1/3

Multiply both sides by 100:

x = (1/3) * 100 = 33.3%
