Answer:
here,
<y +<z = 150 ° ( sum of two sides of interior angle is equal to exterior angle)
or,65°+<x=150°
or, <x=150°-65°
or, <X = 85°
Now,
<x +<y+<z=180° [ the sum of three angles of a triangle is 180°]
or, < x+65°+85°=180°
or, <x =180°-150°
or,< x=30°
Then,
<x+<y=<z
30° +65° =95 °
or, 180° -95° = 85 °
To get <XZW,
180° - 85 ° = 95°[ The exterior angle is equal to the differnce of 2 interior angles through 180 °]
Answer : Option C, The sample will mainly consist of granite.
Explanation:
Sample collected from was continental crust (a part crust) as the samples were from 60 km deep. Continental crust ranges from 30 km to 70 km and this layer is mainly includes granite. This continental crusts is mainly responsible for formation of distinct land-forms like continents.
Statement A ,B and D informs us about the state and temperature of metals(iron) in core that is inner most layer of the earth.
They affect the biosphere because the biosphere is were the living animals are and plants live and it could harm them.

The place where two tectonic plates meet is called a plate boundary.
