Given Angle 1 = Angle 2,<br> find x.
drek231 [11]

Answer:

x = 6

Step-by-step explanation:

Given ∠ 1 = ∠ 2 then the segment is an angle bisector and the ratios of sides to base are equal, that is

\frac{3}{x-4} = \frac{x}{4} ( cross-  multiply )

x(x - 4) = 12 ← distribute left side

x² - 4x = 12 ( subtract 12 from both sides )

x² - 4x - 12 = 0 ← in standard form

(x - 6)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 2 = 0 ⇒ x = - 2

However, x > 0 , thus x = 6

I don't know how to do this question.
sergij07 [2.7K]
The perimeter is the measure around the shape, so just add all the sides together-
6+5x+x+2
6x+8
Since this is a right triangle, you multiply the legs (6 and x+2) and divide by 2
6(x+2)
6x+12
/2
3x+6

coach Cliffman made a deposit of $1800 into an account that earns 2% annual simple interest. find the amount of interest that co
NeX [460]

Answer:

The amount of interest Coach Cliffman earned after 3 years is $108.

Step-by-step explanation:

The equation for simple interest is A = P(1 + rt). To determine the revenue earned, subtract the principal amount ($1800) from the total accured amount (principal + interest). The equation for simple interest is A = P(1 + rt), <em>P </em>meaning principal interest, <em>r</em> being the rate of interest per year in decimal form, and <em>t</em> as time in years.

Let P = $1800, r = .02, and t = 3 and you'll end up with a total accrued amount of $1908. Finally, subtract 1908-1800 to get your answer of $108.

The Blackburn family has a square field where they keep their cattle. The area of the field is 40,000ft squared, and mr Blackbur
Scilla [17]
Area of a square =a^2 
40000=a^2
a=200 inch

Now if u can imagine a square shape with side of 200 inch each.it makes right angles 
so use pythagorean theorm 

c^2=a^2+b^2
c^2=(200)^2+(200)^2
c=282.84 inch

ength of a fence is 282.84 inch

Which of the following pairs of units of measurement are equivalent to each other?
evablogger [386]

Answer:

The correct options are:

  • cubic decimeter and liter  
  • cubic centimeter and milliliter

Step-by-step explanation:

1) The 1 cubic decimeter is equal to the 1 liter.

dm^3= 1 L

2) The 1 cubic centimeter is equal to the 1 milliliter.

cm^3=1 mL

3) Since,1 cubic decimeter is equal to the 1 liter.

So,dm\neq 1L

4) Since, 1 quart = 0.946353 L

quart\neq liter

5) Since,The 1 cubic centimeter is equal to the 1 milliliter.

So, 1 millimeter ≠ 1 deciliter  

6) Since,1 gram = 0.035274 ounces

So, 1 gram ≠ 1ounce
