It's a complementary angle, so just solve for x and subtract the CBD from 90,
First, we have to solve for x.
2x + 14 + x + 7 = 90
Combine like terms
3x + 21 = 90
Balance, subtract 21 from each side.
3x = 69
Divide 3 from each side
x = 23.
So know that we know x is 23, we can go about it 2 ways, subtracting the other angle with 90 or just substituting the variable, I'd just substitute the variable for it so just do 23 + 7. That equals 30, angle ABC = 30.
Both their ages totaled in 5 (years) - 5 (years)
63 - 5 = 58
Current ages totaled = 58 (years)
Daniela is 23 years older than her daughter (as given above) so...
Current ages totaled (58 years) - How many years Daniela is older than her daughter ( 23 years )
58 - 23 = 35
So, Daniela’s age is currently 35 years and her daughter’s age would be 23 years.
The complete factor from:
2x3 + 6x2 + 10x + 30
2x(x+3) + 10(x+3)
(x+3)(2x+10)
2(x+5)(x+3)
hope this help

Answer: the second one
Step-by-step explanation:
The first one is reflection over the x-axis, rotated, and translated. The third one is rotated 90 degrees
