k = 73
The sum of the angles in a triangle is 180°
sum the 2 given angles and subtract from 180 for k
k = 180 - (62 + 45 ) = 180 - 107 = 73
Answer:
Distance Formula is
Step-by-step explanation:
d=√((x_2-x_1)²+(y_2-y_1)²)
Answer:
x = 30
Step-by-step explanation:
here 50 is hypotenuse as it is opposite of 90 degree.
x and x + 10 are the two other smaller sides of a right angled triangle respectively.
using pythagoras theorem,
a^2 + b^2 = c^2
x^2 + (x + 10)^2 = 50^2
x^2 + x^2 + 20x + 100 = 2500
2x^2 + 20x + 100 = 2500
2x^2 + 20x + 100 - 2500 = 0
2x^2 + 20x - 2400 = 0
2(x^2 + 10x - 1200) = 0
x^2 + 10x - 1200 = 0
x^2 + (40 - 30) - 1200 = 0
x^2 + 40x - 30x - 1200 = 0
x(x + 40) - 30(x + 40x) = 0
(x + 40)(x - 30) = 0
either x + 40 = 0 OR x - 30 = 0
x = 0 - 40
x = -40
x - 30 = 0
x = 30
x = -40,30
since the length and distance is not measured in negative ur answer will be 30

Answer:</h3>
8m and 12a
<h3>
Step-by-step explanation:</h3>
Like terms are terms that can be combined to condense a mathematical expression or equation.
Unlike Terms
Unlike terms are defined as terms that have different variables or powers.
- This means that for terms to be unlike they must either be multiplied by a different variable, like x and y, or have different exponents.
If terms meet either of these requirements, they are unlike. On the other hand, for terms to be like they must have both the same variable and power. The coefficients for the terms are not important.
Final Answer
All of the answer choices are to the first power, so the exponents are not important for this question. However, the last 3 answer choices all share the same variable. This means that they are all like terms.
The first answer choice, 8m and 12a, have different variables. This means that they cannot be combined and are unlike terms.
