find the missing angle for the irregular polygon. show your work.
Answer:
x = 114 , ∠A = 132 , ∠B = 114 and ∠D = 124
Step-by-step explanation:
The polygon has 7 sides
A 7 sided polygon has angles that add up to 900 degrees.
So if we add all the measures of the angles and set it to 900 we can solve for x
900 = x + 18 + 132 + 130 + 130 + x + 10 + 138 + x
step 1 : combine like terms
18+132+130+130+10+138 = 558
x + x + x = 3x
We now have 3x + 558 = 900
step 2 : subtract 558 from both sides
900 - 558 = 342
we then acquire 342 = 3x
step 3 : divide both sides by 3
342 / 3 = 114 and 3x / 3 = x
we're left with x = 114
Now we plug in the value of x into the x's to find the measures of the unknown angles
∠B = x and x = 114 so ∠B simply has a measure of 114°
∠A = x + 18
x = 114
∠A = 114 + 18 = 132°
∠D = x + 10
x = 114
∠D = 114 + 10 = 124°
So we can conclude x = 114 , ∠A = 132 , ∠B = 114 and ∠D = 124

Right now Seth's age is 4/5 the age of his brother Eric. Twenty-one years ago, Eric was twice as old as Seth. What are their ages now?
Answer:
Present Time
Let X= Eric's age (4/5)X= Seth's age
Question: What are their ages now?________________________________________________________________________
Past (21 years ago)
X-21 =Eric's age (4/5)X-21=Seth's age
2*[4/5(X-21]=Eric's age
Therefore, X-21= 2*[4/5(X)-21]=Eric's age Substitution
_______________________________________________________________________
X-21= 8/5 X - 42 Solve for "X" by adding 42 to both sides.
X-21+42=(8/5) X
X+21 = (8/5)X Subtract "X" from both sides.
21=(3/5)X Multiply both sides of equation by reciprocal of (3/5), which is 5/3
21*(5/3)= X Finish the problem to find value of "X," which is Eric's age.
Then find 4/5 (X)= Seth's age
Seth age = 4/5 × Eric's age
seth age = x
eric age = y
x = 4y/5 .....eqa 1
2(x-21) = y-21 ......eqa 2
2(4y/5 - 21) = y-21
8y/5 - 42 = y -21
8y/5 - y = 21
1.6 y - y = 21
0.6 y = 21
y = 35 years Eric's age
x = 28 years Seth's age

Not good with functions however I'm sure this is easy for most people.
Solve the equation or formula for the indicated variable.
T= 2rπh + 2πr^2; for h
Steps would be much appreciated
Answer:
h = [tex]\frac{T - 2\pi r^{2}}{2\pi r}[/tex]
Step-by-step explanation:
T= 2rπh + 2πr²
Subtract terms that don't include the indicated variable from both sides:
T= 2rπh + 2πr² ⇒ T - 2πr² = 2rπh
Divide values being multiplied by indicated variable from both sides:
T - 2πr² = 2rπh ⇒ [tex]\frac{T - 2\pi r^{2}}{2\pi r}[/tex] = h

Expand 2(q+3) please
Answer:
2q + 6Step-by-step explanation:
Expand the expression with the help of distributive property.
2(q + 3)=> (2 x q) + (2 x 3)=> 2q + 6Hence, the expanded expression is 2q + 6.
Answer:
2q +6
Step-by-step explanation:
The distributive property is used for this purpose. The factor outside parentheses (2) multiplies each of the terms inside parentheses (q, 3).
2(q +3) = 2·q +2·3 = 2q +6
_____
Additional comment
It might help to think of the parentheses as a "bag" containing one "q" and 3 tokens. The number outside parentheses tells you how many "bags" you have. Expanding the expression is equivalent to dumping out the bags and describing the total contents:
2(q +3) = (q +3) +(q +3) . . . . multiplication is the same as repeated addition
= (q +q) +(3 +3)
= 2q +6

x = 55, because 60 + 65 = 125 and 180 - 125 = 55
x = 125, because 180 - 160 +65) = 55 and 180 - 55 = 125
65
x = 305, because 60+ 65 = 125, and 125 + 180 = 305
x = 175, because 180-65 = 115 and 115 + 60 = 175
Answer: x= 55 because 60 + 65 =125 and 180 - 125 = 55
Step-by-step explanation:
The sum of three angles in any triangle is 180. Therefore you add the two angles that you have and use that number to subtract it by 180. Then you will have your answer. Also you can get the answer to y by subtracting the value of x from 180.
