Answer:

AC = 10 cm

Step-by-step explanation:

We are givne with a triangle ABC is an equilateral triangle with side AB, BC, and AC. We are given that side BC is equal to 10 cm . We are required to find the measurement of side AC.

The basic property of any equilateral triangle is that all the sides are equal. Hence

AB = BC = CA

BC=10 cm

Hence, AB = 10 cm and also AC=10 cm

Answer:

AC =10cm.

Step-by-step explanation:

Given : Triangle ABC is an equilateral triangle with side AB, BC, and AC. If side BC is equal to 10 cm .

To find :  what is the measure of side AC.

Solution : We have given

Triangle ABC is an equilateral triangle with side AB, BC, and AC.

Equilateral triangle : The triangle which has all equal sides .

So,we have given One side BC = 10 cm

So all the side would be AB= 10 cm.

AC = 10 cm.

Therefore, AC =10cm.

15. In the rhombus shown below, mz1 = 160°. What are the measures of 22 2 points
egoroff_w [7]

Answers:

angle2 = 160 degrees

angle3 = 10 degrees

============================================

Explanation:

The two triangles are congruent. We can prove this using SSS. The upper triangle is a mirrored copy of the lower triangle.

Since angle1 = 160 degrees, this means angle2 = 160 also. This is because the corresponding pieces of congruent triangles match up. Or you could use the second part of the hint which says "Opposite angles in a rhombus are congruent".

Let x be the measure of angle 3. For either isosceles triangle, it has congruent base angles measured x degrees. They add to the 160 degrees mentioned earlier to get a total of 180.

160+x+x = 180

2x+160 = 180

2x = 180-160

2x = 20

x = 20/2

x = 10

Angle 3 is 10 degrees.

You have 2,112 grams of a radioactive kind of mercury. How much will be left after 188 days if it's half-life is 47 days?
Anastasy [175]

Answer:

  • 132 g

Step-by-step explanation:

  • Initial amount = 2112 g
  • Time = 188 days
  • Half-life = 47 days

188 days / 47 days = 4 periods

<u>Mercury left after 188 days:</u>

  • 2112 * (1/2)^4 =
  • 2112* 1/16 =
  • 2112/16 =
  • 132 g

Answer:

I believe the answer is $2.25

Step-by-step explanation:

To figure this out, first you need to find 25% as a decimal. 25% as a decimal is .25 . Then, you multiply 9 by .25 . 9 * .25 = $2.25. You are saving $2.25 with the discount.

Hope this helps :)

Analyze the key features of the graph f(x) = 1/x+3 -2
tia_tia [17]
<h2>Explanation:</h2><h2></h2>

Here we have the following rational function:

f(x) = \frac{1}{x+3} -2

So the graph of this function is shown in the First Figure below. Let's define another function which is a parent function:

g(x)=\frac{1}{x}

Whose graph is shown in the second figure below. So we can get the graph of f from the graph of g this way:

Step 1. Shift the graph 3 units to the left:

f_{1}(x) = \frac{1}{x+3}

Step 2. Shift the graph 2 units down:

f(x) = \frac{1}{x+3}-2

Finally, the features of the graph of f are:

The graph of this function comes from the parent function g and the transformations are:

  • A shifting 3 units to the left
  • A shifting 2 units down
