Please look at this pict. hope it can help u
A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11
Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°
Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°
Answer: 6 outcomes
Step-by-step explanation: Since the first outcome is 2 and the second is 4 2 times 3 is ix since it is multiplying by 2 (2,4,6,8)
Question:
The recursive function , represents the nth term of a sequence. Determine the explicit function
Answer:
Step-by-step explanation:
Given
Required
Write an explicit formula
Let n = 1
Let n = 2
Let n =3
Let n = 4
So, we have:
Following the above pattern:
Open bracket
Answer:
x = 18
y = 15
Step-by-step explanation:
The two lines that are parallel tell us that x is 18 because there is a 90-degree angle. 90° / 5 = 18, so x must be 18.
The y is a bit more complicated, but still fully solvable. "All quadrilaterals' interior angles sum to 360°" so we can find y by doing the following:
<em>Equation: </em>90° + 90° + (4y - 10)° + 5(y + 11)° = 360°
<em>Distribute: </em>90° + 90° + 4y - 10° + 5y + 55° = 360°
<em>Combining like terms: </em>225° + 9y = 360°
<em>Subtracting 225 from both sides:</em> 9y = 135°
<em>Divide both sides by 9: </em>y = 15
I hope this helps, have a nice day :D
