What is the measures of angle C
deff fn [24]

Answer:

25

Step-by-step explanation:

I got 25, because I worked it out and if you plug in 25 to the equation when adding all of the angles and making them equal to 180 degrees, you end up with the remaining degrees to be 25, leaving angle C at 25 degrees. I hope this helps.

mr john has a son and a daughter , the son being 4 years older than daughter.Five years ago the age of mr john was 23 years more
jeka94

First, let us define our variables.

Let

x = age of the father

y = age of the son

z = age of the daughter

 

5 years ago..

(x – 5) = age of the father

(y – 5) = age of the son

(z – 5) = age of the daughter

 

After 18 years...

(x + 18) = age of the father

(y + 18) = age of the son

(z +18) = age of the daughter

 

From the first condition

y = z + 5 à eqn 1

5 years ago

(x-5) = 23 + (y-5) + (z-5)

x –y –z = 18 à eqn 2

after 18 years

(x+18) = 17*[(y +18 –z – 18)]

x – 17y + 17z = -18 à eqn 3

 

solving the 3 equations simultaneously

x = 67

y = 27

z = 22
