Answer:
123
Step-by-step explanation:
I don't know what place you want it rounded to, but if you are rounding to the nearest whole number, it'd be 123 because the 8 after the .9 is greater than 5 which makes the 9 go up. Since 9 is the last greatest single digit number the 2 before the (.) is rounded up as well to a 3.
PART A. a=123, b=123, c=57
The angle that is labeled as 123 degrees is an alternate interior angle to b. Alternate interior angles are congruent, meaning that b=123.
a and b are vertical angles. Vertical angles are congruent, meaning that the angles for angle a and angle b are the same. So a=123.
C is a linear pair angle. Meaning that 123 and angle c equals to 180 degrees.
So you do 180-123 which would equal to 57.
PART B. d=98, e=98, f=98
The angle with the degree of 82 and angle f are linear pair angles. Meaning that when added together, they equal to 180.
So you do 180-82, which would equal to 98. F=98.
Angles d and f are corresponding angles. Corresponding angles are congruent. So if f equals to 98, then d also equals to 98.
Angles d and e are vertical angles. Vertical angles are congruent. So angle e also equals to 98 degrees.
PART C. g=75
The angle with the degree of 75 are alternate interior angles to angle g. Alternate interior angles are congruent. Meaning that g equals to 75 degrees.
Answer:
k = 4
Step-by-step explanation:
In the equation: x² - 2x - 24
Replace the x with x + 3
(x+3)² - 2(x+3) - 24
x² + 6x + 9 - 2x - 6 -24
Let's rearrange it
x² + 6x -2x - 24 + 9 - 6
x² - 4x - 21
f(x+3) = x² - 4x - 21
