Answer:

x=52°

Step-by-step explanation:

∠LNP+142°=180°

∠LNP=180°-142°  

         = 38°

∠LMN=x

x+90°+38°=180°

x+128°=180°

x=180°-128°

 =52°

Answer:

 x = 52°

Step-by-step explanation:

In the given figure,

142° is an exterior angle of triangle LMN

∠L = 90°

∠M = x

Exterior angle theorem: Sum of two opposite interior angle of a triangle is equal to exterior angle of triangle.

Therefore,

∠LMN + ∠MLN =  ∠MNP

          x  +  90° = 142°

                     x = 142° - 90°

                     x = 52°

Hence, The missing angle is 52°

A train travels a distance of 60 km at uniform speed. If the speed of the train was reduced by 10 kmh-1, the time taken to trave
tester [92]

Answer:

<u>Initial</u><u> </u><u>speed</u><u> </u><u>is</u><u> </u><u>3</u><u>2</u><u> </u><u>m</u><u>/</u><u>s</u>

At uniform speed, acceleration is 0, (a = 0).

When speed reduced, (v - u) = 2.78 ms-¹, t = 1800 sec, s = 60 ,000 metres.

From first equation of motion:

{ \boxed{ \bf{v = u + at}}} \\  { \tt{(v - u) = at}}

substitute:

{ \tt{2.78 = (a \times 1800)}} \\ { \tt{acceleration = 0.0015 \:  {ms}^{ - 2} }}

from second equation of motion:

{ \boxed{ \bf{s = ut +  \frac{1}{2} a {t}^{2} }}}

substitute:

{ \tt{60000 = 1800u + ( \frac{1}{2} \times 0.0015 \times  {1800}^{2})  }} \\ { \tt{1800u = 57570}} \\ { \tt{u = 32 \: m {s}^{ - 1} }}
