Question

In the below figure < (a) 600 (b) 500 (c) 700 (d) none of these​

Answer 1

Step-by-step explanation:

Although its formula (H2O) seems simple, water exhibits very complex chemical and physical properties. For example, its melting point, 0 °C (32 °F), and boiling point, 100 °C (212 °F), are much higher than would be expected by comparison with analogous compounds, such as hydrogen sulfide and ammonia.

Answer 2

According to the given figure, the angle AEB is 70° (option c).

Let's solve this problem step by step.

Given,

Angle DCB = 60°

Angle BAE = 50°

To find,

Angle AEB.

Solution,

We can easily solve this problem using the following steps.

Now,

CD || AB

Then,

Angle DCB and angle ABE are alternate interior angles.

Angle DCB = Angle ABE = 60°

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

Then,

Angle ABE + Angle BAE + Angle AEB = 180°

60 + 50 + Angle AEB = 180°

110 + Angle AEB = 180°

Angle AEB = 180° - 110°

Angle AEB = 70°

( Angles are written in degrees, ° like measurements are written in different units.)

Hence, the angle will be 70°.
