a car travels a distance and of 180 km in 2 hours on a straight road .how many km can it travel in 3 hours at the same speed​

270 km

Step-by-step explanation:

If the car has travelled 180km on a straight road for 2 hours then its speed is 90 km/h.

Hence,

in 3 hours it can travel 180 + 90 = 270 km.

270 KM

Step-by-step explanation:

180 divided by 2= 90

90*3= 270

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
