Answer : The value of
is
.
Explanation :
As we are given 6 right angled triangle in the given figure.
First we have to calculate the value of
.
Using Pythagoras theorem in triangle 1 :




Now we have to calculate the value of
.
Using Pythagoras theorem in triangle 2 :





Now we have to calculate the value of
.
Using Pythagoras theorem in triangle 3 :





Now we have to calculate the value of
.
Using Pythagoras theorem in triangle 4 :





Now we have to calculate the value of
.
Using Pythagoras theorem in triangle 5 :





Now we have to calculate the value of
.
Using Pythagoras theorem in triangle 6 :





Therefore, the value of
is
.
When a cyclone's strongest winds do not exceed 61 kilometers (38 miles) per hour, it is called a tropical depression
Tropical cyclones are classified based on their wind speed. When the fastest sustained winds does not exceed 38 miles per hour (61 km per hour), it is called a tropical depression.
If the fastest wind is greater than 38 miles per hour (61 km per hour), it is called a tropical storm.
However, if the maximum sustained wind speed reaches 74 mile per hour (119 km per hour) it is referred to as a hurricane.

Answer:
North Africa receives substantially less insolation than Sub-Saharan Africa.
Explanation:
North Africa receives less solar radiation from the sun as compared to Sub-Saharan Africa because north Africa is far from equator whereas the Sub-Saharan Africa is located near and on the equator zone. Those regions who are on the equator experience direct solar radiation of sun that leads to higher insolation as compared to areas which is far away from equator receives lower insolation so that's why North Africa have low insolation as compared to Sub-Saharan Africa.
I think (a) because the ocean floor is the crust which is mainly were shallow earthquakes occur. I'm not sure if this is right or not sorry :)
