The measure of <2 is 92 degrees
<h3>How to solve for 2?</h3>
The complete question is in the attached image
The angles are given as:
<1 = 4x - 4
<2 = 4x
The sum of angles on a straight line is
<1 + <2 = 180
So, we have:
4x - 4 + 4x = 180
Evaluate the like terms
8x = 184
Divide by 8
x = 23
Substitute x = 23 in <2 = 4x
<2 = 4 * 23
Evaluate
<2 = 92
Hence, the measure of <2 is 92 degrees

Jake because 45.21×10=452.1 which is not a whole number, and 8.22×10=82.2 which is also not a whole number, but 45.21×100=4521 which is a whole number, and 8.22×100=822 which is also a whole number. When you multiply a number with 1 and 0s behind it (ex: 10,100,1000, etc) You just more the decimal place the number of 0s you have (ex: 2.0×100= 200, 3.5×1000=3500)
Answer:
x = 8
Step-by-step explanation:
13 - 5 = 8
x = 8
hope this helps...
#1. 4x^2 + 17 - 15 = 0
Use the roots given, and plug them in to a factored form. Then, foil! It can also be helpful to multiply the equation to get rid of decimals/fractions.
(x - 3/4)(x + 5) = 0
x^2 - 3/4x + 5x - 3 3/4 = 0
x^2 + 4.25 - 3.75 = 0 (multiply everything by 4)
4x^2 + 17 - 15 = 0
#2. y = 0, -4
Both 4y^2 and 16y contain a 4 in the coefficient and a y in the variables. Therefore, we can factor out a 4y from each.
4y(y + 4) = 0
Then, set both parts of the factored equation equal to 0.
4y = 0
y = 0
y + 4 = 0
y = -4
#3. a = 0, -3
Both 6a^5 and 18a^4 contain a 6 in the coefficient and an a in the variables. Therefore, we can factor out a 6a^4 from each.
6a^4(a + 3) = 0
Then, set both parts of the factored equation equal to 0.
6a^4 = 0
a = 0
a + 3 = 0
a = -3
#4. x = -8
We are looking for two terms that multiply to equal a * c, and add up to equal b. We know that 8 + 8 = 16, and 8 * 8 = 64. There are no negatives in this equation, therefore both signs in our factored form are positive.
(x + 8)(x + 8) = 0
x + 8 = 0
x = -8
#5. x = -8, 8
First, subtract 64 from both sides. The key word here is 'factoring.' If this was not present, there is a different way (which may be easier for some).
x^2 = 64
x^2 - 64 = 0
Next, use the difference of two squares property to factor (x - c)(x + c), and set the two binomials equal to 0.
(x - 8)(x + 8) = 0
x - 8 = 0
x = 8
x + 8 = 0
x = -8
Hope this helps!! :)
