Fred begins walking toward johns house at 3 miles per hour. John leaves his house at the same time and walks towards Fred's hous

Dennis_Churaev [7]

Answer:it all take them 0.8 hours

Step-by-step explanation:

Let x represent the distance covered by Fed.

Their houses are 4 miles apart. It means that by the time they meet, John would have covered 4- x miles.

Let t represent the time taken by Fred to cover x miles and also the time taken by John to cover 4 - x miles.

Distance = speed × time

Therefore,

Distance covered by Fred would be

x = 3 × t = 3t

Distance covered by John would be

4 - x = 2 × t = 2t

Substituting x = 3t into 4 - x = 2t, it becomes

4 - 3t = 2t

2t + 3t = 4

5t = 4

t = 4/5 = 0.8 hours

Help plz<br>Find the measurement of the angles of a triangle if they are in the ratio 5:4:3

Lerok [7]

Answer:

<u>See below:</u>

Step-by-step explanation:

Let the angles be 5x , 4x , 3x.[Since the angles are in ratio 5:4:3 ] respectively.

We know that sum of all angles of a triangle is 180°.

So,

$5x + 4x + 3x = 180 {}^{ \circ}$

Now Find the value of x of this equation.

$\sf \implies \: 5x + 4x + 3x = 180 {}^{ \circ}$

$\sf \implies12x = 180 {}^{ \circ}$

$\sf \implies \: x = \cfrac{180 { {}^{ \circ} }}{12}$

$\sf \implies \: x = \cfrac{ \cancel{180 {}^{ \circ}} }{ \cancel{12}}$

$\sf \implies \: x = 15 {}^{ \circ}$

Now,

Multiply each ratio given by 15 which is the value of x we got.

That is;

$\therefore \sf\implies \: First \: Angle = 5 \times 15 {}^{ \circ} = \boxed{75 {}^{ \circ}}$

$\sf \sf \implies \: Second\: Angle = 4\times 15 {}^{ \circ} = \boxed{60 {}^ \circ}$

$\sf \implies \: Third\: Angle = 3 \times 15 = \boxed{ {45}^ \circ}$

Hence,the measurements of the angles of the triangle would be 75°[First Angle],60°[Second angle],and 45° [Third Angle].
