First angle = x
Second angle = x - 42
Sum both complementary angles = 90
x+x-42=90
2x=132
x=66⁰ - First angle
x-42=66-42=24
24⁰ - Second angle
Answer:14 m
Step-by-step explanation:
Dada
larga 
superficie 
Suponga que el ancho es w
La superficie está dada por el producto de la longitud y la anchura.

Por lo tanto, el ancho es de 14 m.
Answer:
you do the opposite for example: If its x+9=11...You subtract 9 from 11.....if its x-9=11....you do add the 9 to the 11
Step-by-step explanation:
Given series is 2.4,-4.8,9.6,-19.2
To find whether it has common difference or common ratio let us find few differences and few ratios of consecutive terms.
Common difference of first 2 terms = 2nd term - first term = -4.8-2.4 = -7.2
Common difference of 2nd and 3rd terms = 3rd term - 2nd term = 9.6-(-4.8) = 14.4
Since those common differences are not equal the given series does not have common difference at all.
To check if it has common ratio or not let us find few ratios of consecutive terms.
Common ratio of first 2 terms =
= 
Common ratio of 2nd and 3rd terms = 
So, the given series has common ratio as -2.0
Answer:
I believe it is: B= 16.45
