The measures of all angles of the triangle are :
Given: G = 117°
C = 22°
E = 40°
To find, B, F, D = ?
Now, F = G because opposite angles, Thus, F = 117°
And, Triangle sum property, F+B+C = 180°
Thus, B = 180°-F - C
= 180° -117° - 22°
= 41°
Similarly, D = 180° -40° - 63° (Triangle sum property,)
= 77°
Cairo is at the top of the delta and you can see the three big pyramids and the sphinx at Giza across the river from Cairo. Just to the right of the delta is the Suez Canal. It is one of the world's largest river deltas, it covers 240 km (150 mi) of Mediterranean coastline from Alexandria in the west to Port Said in the east. The delta is about 160 km (99 mi) in length from north to south. It starts marginally down-river from Cairo. It covers approximately 240 km (150 mi) of shoreline from west to east.
Answer:
Cleavage of a mineral is defined as the direction along which the mineral breaks over the flat mineral surface. It is directly dependent on the mineral's crystallographic structure.
Slaty cleavage refers to the cleavage that is commonly found in the low grade metamorphic rock slate. Here, the fine grained minerals are so closely spaced and the lines of weakness are all parallel to each other, that allows the minerals to break in fine and thin layers. During the time of formation of slate, the smaller fractures are formed due to the increasing pressure. When groundwater moves through these fractures it forms a weak zone due to which these slaty cleavage forms.
When the rocks undergoes deformation and changes in the pressure and temperature condition then the cleavages are formed on the mineral's surface. The calcite contains rhombohedral cleavage are considered to be the perfect cleavage. Whereas the cleavage in amphibole is uneven and comprised of two directions that intersect each other at 56° and 124°.

Climate change affects every country and can have devastating effects on communities and individuals. According to the World Health Organization, as of the year 2030, climate change is expected to contribute to approximately 250,000 additional deaths per year, from malnutrition, malaria, diarrhea and heat stress.
