angle D = 92°
Step-by-step explanation:
Since the two figures are congruent.
angle D = angle K
20x + 12 = 25x - 8
5x = 20
x = 4
Substituting this value into angle D, we see that
angle D = 20x + 12
= 20(4) + 12
= 92°

8⊕6 is 10
Step-by-step explanation:
We will use the substitution method to solve this problem
∵ The operation ⊕ is defined by p⊕q = 
∵ You want to find 8⊕6
- Then do these steps:
- Substitute p by 8
- Substitute q by 6
- Calculate the square root of 8² + 6²
∵ p = 8
∴ p² = 8² = 64
∵ q = 6
∴ q² = 6² = 36
∵ p⊕q = 
- Substitute p by 8 and q by 6 in the rule above
∴ 8⊕6 = 
- Substitute 8² by 64 and 6² by 36
∴ 8⊕6 = 
∴ 8⊕6 = 
∵ 
∴ 8⊕6 = 10
8⊕6 is 10

Answer:
Step-by-step explanation:
y - 1 = 2(x + 2)
y - 1 = 2x + 4
y = 2x + 5
Scientific notation uses expression which gives easy access of order. The scientific notation of given number is: Option A: 1.6E-8
<h3>How to convert a number to scientific notation?</h3>
It is usually of the form
exponent of 10 starts)
(we have 1 ≤ |a| < 10 ) (where |a| is magnitude of a without sign)
This notation is used to get some idea of how large or small a number is in terms of power of 10.
<h3>What are some basic properties of exponentiation?</h3>
If we have
then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
Exponentiation(the process of raising some number to some power) have some basic rules as:

The given number is converted in scientific notation as:

Thus, the scientific notation of given number is: Option A: 1.6E-8
