Answer:

x=14

m<1 = 5×14

= 70°

m<2 = 14 +6

= 20

Step-by-step explanation:

angle 1 + angle 2 = 90°

5x +(x+6) = 90

6(x+1) = 90

x+1 = 90/6

x = 15 - 1

<u>x = 14</u>

Andrew is elder to Brian by 2 years. Andrew's father Frank is twiceas old as Andrew, and Brian is twice as old as his sister Sar
babunello [35]

Let "x" represent the age of Brian.

Andrew is elder than Brian by 2 years, we can symbolize his age as "x+2"

Frank is twice as old as Andrew, we can symbolize his age as "2(x+2)"

Sarah has half the age of Brian's, we can symbolize her age as "x/2"

Frank ans Sarah's ages differ by 40 years, we can symbolize this as:

2(x+2)-\frac{x}{2}=40

Solve the term is parenthesis

\begin{gathered} 2x+4-\frac{1}{2}x=40 \\ 2x-\frac{1}{2}x+4=40 \\ \frac{3}{2}x=40-4 \\ \frac{3}{2}x=36 \\ x=24 \end{gathered}

x=24 years

Andrew's age is

x+2=24+2=26

Andrew is 26 years old
