Answer:

18°

Step-by-step explanation:

The m∠A ≅ x+32

The angle opposite 36° is 36° & the angle opposite x+126 is x + 126: Vertical angles theorem

The three angles in the triangle with m∠A are 36°, x+126°, and x+32°(m∠A)

36+x+126+x+32 = 180 : Angles in a triangle theorem

194+2x = 180

2x = -14

x= -7

m∠A ≅ -14+32

m∠A≅ 18°

I hope this helps!!!

When I have walked 20% of the way to school, I have 1200 metres more to walk than when I have 20% of the walk remaining.

Orlov [11]

Given:

I have walked 20% of the way to school.

I have 1200 metres more to walk than when I have 20% of the walk remaining.

To find:

The distance from home to school.

Solution:

Let x be the distance from home to school.

I have already walked 20% of the way to school and i have 1200 metres more to walk than when I have 20% of the walk remaining.

It means 1200 is $100\%-20\%-20\%=60\%$ of the total distance from home to school.

$1200=\dfrac{60}{100}x$

$1200=0.6x$

$\dfrac{1200}{0.6}=x$

$2000=x$

Therefore, the distance from home to school is 2000 metres.

100m In 9 3/5 seconds

Nostrana [21]

Answer:

Speed = 10.42 m/secs

Step-by-step explanation:

We have been given with:-

Distance = 100m

Time taken = 9 $\frac{3}{5}$ secs

1) First, we need to convert the mixed number 9 $\frac{3}{5}$ to an improper fraction.

Method to convert a mixed number to an improper fraction

 $a\frac{b}{c} = \frac{c*a+b}{c}$ 

Applying the above formula, we get

9 $\frac{3}{5}$ = $\frac{5*9+3}{5}$

= $\frac{45+3}{5}$

= $\frac{48}{5}$

2) Now we need to convert $\frac{48}{5}$ into a decimal by dividing 48 by 5.

We get time taken as 9.6 secs

3) We need to find the speed using the below formula:-

Speed = $\frac{Distance}{Time taken}$

Plugging the values of Distance and Time taken into the formula, we get

Speed = $\frac{100}{9.6}$

= 10.416 m/secs

4) Upon rounding it to the nearest hundredth, we get

Speed = 10.42 m/secs
