Answer:
180°
Step-by-step explanation:
The sum of the exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle in a regular polygon is: 360 number of sides. If you know the exterior angle you can find the interior angle using the formula: interior angle + exterior angle = 180°

Answer:
x=27
∠JLK=2x+1=2(27)+1=55
Step-by-step explanation:
∠A+∠K=180
3x+13+∠K=180
∠K=167-3x
∠K+∠L+∠J=180
167-3x+39+2x+1=180
207-x=180
x=27
∠JLK=2x+1=2(27)+1=55
Don't worry, you aren't gonna fail. Take a deep breath and relax. Geometry is tricky but you got this. Have a nice night.
Answer:
x = 27°∠JLK = 55°Step-by-step explanation:
∠AKL is exterior angle and as per property it is equal to sum of two non-adjacent angles:
∠AKL = ∠ KJL + ∠JLK3x + 13° = 39° + 2x + 1°Solving for x
3x - 2x = 39° + 1 - 13x = 27°And finding the value of ∠JLK:
∠JLK = 2x + 1 = 2*27° + 1° = 55°PLS HELP NO ONE IS GIVING ME A STEB BY STEP SOLUTION AND DON'T ANSWER IF YOU DON'T KNOW!!!
Given two similar kites, ABCD and EFGH, having perimeters 24 and 64 respectively, what is the ratio
of the measures of two corresponding side lengths of ABCD to EFGH? *Write as a fraction*
Answer:
3/8
Step-by-step explanation:
The ratio of the lengths of the sides is the same as the ratio of the perimeters.
perimeter ABCD : perimeter EFGH = 24/64 = 3/8
side ABCD : corresponding side EFGH = 3/8

N=480×10^9
Write N as a product of powers of its prime factors.
Answer:
I got 5^10 x 2^14 x 3
Step-by-step explanation:
1. Do a tree to find 480 as a product of its prime factors
2. You should get 480= 5x2x3x2x2x2x2
3. 10 expressed as a product of its prime factors is 5x2
4. so 10^9 expressed as a product of its prime factors would be
5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
5. You can then write out 480x10^9 as a product of its prime factors
5x2x3x2x2x2x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2x5x2
6. change this to use powers
5^10 x 2^14 x 3
N = 5^(10) × 2^(14) × 3
This is about prime factors
By definition, a prime factor is a factor of a number and that factor is also a prime number.
A prime number is one that is divisible by only itself and 1.
The number we have is; 480 × 10^(9)
Now, let's list the prime factors or 480 and they are;
2, 3, 5
Now, using these prime factors alone to get 480, we have;
5 × 3 × 2 × 2 × 2 × 2 × 2 = 480
In powers, gives;
5 × 3 × 2^(5)
Now,the 10^(9) with the 480 can also be expressed in terms of it's prime factors which are 2 and 5 as;
(5 × 2)^(9)
Expanding this gives; 5^(9) × 2^(9) = 10^(9)
Thus;
480 × 10^(9) = 5 × 3 × 2^(5) × 5^(9) × 2^(9)
This gives;
5^(10) × 2^(14) × 3

f(x)=6(1-x) what is the value of f(-8)
Answer:
54
Step-by-step explanation:
What the shorthand is telling you is wherever you see an x on the right, you put in -8
f(x) = 6(1- x)
f(-8) = 6(1 - - 8)
f(-8) = 6(1+8)
f(-8) = 6*9
f(-8) = 54
5. Bobby guessed there were 92 jelly beans in a jar. There were actually 107 2 points
jellybeans. Find the percent of error. Round to the nearest hundredth of a
percent if necessary.
HELP IM IN A QUIZZZ
Answer: 14%
Step-by-step explanation:
From the question, we are informed that Bobby guessed there were 92 jelly beans in a jar when there were actually 107. The percentage error will be:
= Difference in error / Actual value × 100
= (107 - 92) / 107 × 100
= 15/107 × 100
= 0.14 × 100
= 14%

In the diagram below, we have ST parallel to QR. angle P= 40 degrees, and angle Q= 35 degrees. Find the measure of angles STR in degrees.
Answer:
[tex]m\angle S = 35^\circ, \ m\angle T = 105^\circ,\ m\angle R = 105^\circ[/tex]
Step-by-step explanation:
Similar Triangles
Lines ST and QR are parallel. Thus, angles S and Q are congruent, and angles T and R are congruent.
Considering the triangle PQR, the sum of its internal angles must be 180°:
[tex]m\angle P + m\angle Q + m\angle R = 180^\circ[/tex]
Substituting the known values:
[tex]40^\circ + 35^\circ + m\angle R = 180^\circ[/tex]
Solving for R:
[tex]m\angle R = 180^\circ - 40^\circ - 35^\circ[/tex]
[tex]m\angle R = 105^\circ[/tex]
Angles S and Q are congruent, thus
[tex]m\angle S = 35^\circ[/tex]
Angles T and R are congruent, thus
[tex]m\angle T = 105^\circ[/tex]
Summarizing:
[tex]\mathbf{m\angle S = 35^\circ, \ m\angle T = 105^\circ,\ m\angle R = 105^\circ}[/tex]

Solve the equation using inverse operations. Check your solutions. In you final answer, include all of your work.
Answer:
x = ±6
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra II
Extraneous solutions and multiple answers/rootsStep-by-step explanation:
Step 1: Define
-x² = -36
Step 2: Solve for x
Divide -1 on both sides: x² = 36Square root both sides: x = ±6Step 3: Check
Plug in x to verify it's a solution.
Substitute in -6: -(-6)² = -36Exponents: -(36) = -36Multiply: -36 = -36Substitute in 6: -(6)² = -36Exponents: -(36) = -36Multiply: -36 = -36Here we see that both -6 and 6 do indeed work as solutions.
∴ x = ±6 are both solutions to the equation.
How do you solve -7x – 13 ≥ 8 ?
Answer:
x ≥ - 3
Step-by-step explanation:
Step 1:
- 7x - 13 ≥ 8 Equation
Step 2:
- 7x ≥ 21 Add 13 on both sides
Step 3:
x ≥ 21 ÷ - 7 Divide
Answer:
x ≥ - 3
Hope This Helps :)
Answer: x≤−3
Step-by-step explanation:
So first you -7*x-13-(8)≥0
then you are supposed to pull out like the factors -7x - 21 = -7 • (x + 3)
then you divide both sides by -7 then you flip the inequality sign remember that :). then subtract 3 from both sides. and then you got x ≤ -3 So I really hoped this helped :)
