Step-by-step explanation:
it's easy to prove in any right triangle with a 30° angle, the side opposite to that angle is half the hypotenuse. CA (1/2)BC, CA/BC=1/2
Step-by-step explanation:
Take an equilateral triangle of side.
Bisec it through a vertex and the midpoint of the opposite side.
You now have two right-angled triangles with angels 30° , 60°, 90° with the edge opposite the 30° of length 1/2 and hypotenuse 1. So
sin (30°) = 1/2/1= 1/2.
Answer: The right angled triangle you describe has angels of 45 degrees, not 30 degrees.
What you proved is sin 45 = 1\2 , which is correct.

solve the system of equations by adding. checking your answer
2x+2y=2
3x-2y=43
the solution of the system is ( , )
Answer:
Step-by-step explanation:
This is very easy, because the coefficients of the y terms are 2 and -2. You can easily eliminate the y terms by adding the equations together:
2x + 2y = 2
3x - 2y = 43
-----------------
5x + 0y = 45, so x = 9
Use the value of x to solve for y:
2(9) + 2y = 2
y = -8
(x,y) = (2, -8)

Given acd and abe, what is ab?
Answer:
AB = 8
Step-by-step explanation:
Using the similarity theorem of a triangle;
AC/AD = AB/AE
AC = AB + BC and AD = AE + ED
AB + BC/AE + ED = AB/AE
Substitute the given values
AB+12/15 = AB/6
Cross multiply
6(AB+12) = 15AB
6AB + 72 = 15AB
15AB - 6AB = 72
9AB = 72
AB = 72/9
AB = 8
There are 5 red and 3 black balls in a bag. Find the probability of drawing a black ball.
Answer:
5 : 3 (8 total)
3/8 or 0.375 or 37.5%
Answer:
the probability of drawing a black ball Pr( B)=3/8
Step-by-step explanation:
The total number of balls =5+3
=8
probability of drawing a Red ball=Pr(R)
=5/8
probability of drawing a Black ball=Pr(B)
=3/8

What percentage of the pieces was he missing if he had 250 puzzle pieces and was missing 15 What percentage of the pieces was he missing
Answer:
Percentage of missed puzzle pieces = 6%
Step-by-step explanation:
Total number of puzzle pieces = 250
Missed puzzle pieces = 15
Percentage of the missing puzzle pieces = [tex]\frac{\text{Missed puzzle pieces}}{\text{Total number of puzzle pieces}}\times 100[/tex]
= [tex]\frac{15}{250}\times 100[/tex]
= 15 × 0.4
= 6%
Therefore, percentage of missed puzzle pieces = 6%
(6n – 7) + (8n + 2) = 23
Answer:100
Step-by-step explanation:
2!2
Answer:
n = 2
Step-by-step explanation:
(6n - 7) + (8n + 2) = 23 (Combine like terms)
14n - 5 = 23 (Add 5 from both sides)
14n = 28 (divided 14 from both sides)
n = 2

Answer: p>−4
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2−7p<26
Step 1: Simplify both sides of the inequality.
−7p−2<26
Step 2: Add 2 to both sides.
−7p−2+2<26+2
−7p<28
Step 3: Divide both sides by -7.

Write an equivalent expression in word form.
(1- 1/3) / 2
Answer:
21
Step-by-step explanation:
One number is 4 more than another, and their sum is 60. What is the smaller number?
If x = the larger number and y = the smaller number, then which of the following systems could be used to solve the problem?
x + y = 60 and -x + y = 4
x + y = 60 and x + y = 4
x + y = 60 and x - y = 4
Unlimited Attempts Remain
Answer:
Step-by-step explanation:
The system is
x+y=60 and x-y=4
If we get the difference between the two equations above we get
x+y-x+y=60-4
2y=56
y=28
