Answer:

Angle 2 = 120 degrees, Angle 1 = 60 degrees

Step-by-step explanation:

Since a straight angle is 180 degrees, you have to add up the 2 angles to 180.

x+x+60=180

2x+60=180

2x=120

x=60

Angle 1 = 60

Angle 2 = 60+60=120

Answer:

She walked for 46 minutes

Step-by-step explanation:

Given

When she leaves home

$h = 7am$

$\theta_1 = 110^o$

When she arrives at school

$H = 8am$

$\theta_2 = 110^o$

Required

Time to walk to school

First, we convert $\theta_1 = 110^o$ to minutes:

$\theta_1 = \frac{110}{6}$

$\theta_1 = 18.33$

$\theta_1 = 18$ --- approximated

From the question, we understand that she left home past 7.

This means that the difference between the hour hand (at 7) and the minutes hand is 18 minutes.

Also, the minute hand is between 0 and 30 minutes

Subtract 18 minutes from 30 minutes;

$Mins = 30-18=12$

She left home at 7:12am

Similarly;

$\theta_2 = \theta_1 = 18\ mins$

From the question, we understand that she arrived before 8.

This means that the difference between the hour hand (at 8) and the minutes hand is 18 minutes

Also, the minute hand is between 30 and 60 minutes mark.

At the 8hour hand, the minutes is 40

Add 18 minutes from 40 minutes;

$Mins = 40 + 18 = 58$

She arrived at 7:58am

The difference (d) is:

$d =7:58am - 7:12am$

$d =46$
