How does the collection of data in environmental science differ from many others in science?

Collection of data in environmental science differ from many others in science:

The study of both natural and social sciences is called as Environmental science. It is based on environmental conditions affecting humans and living and dead organisms.

Environmental scientists gather data and conduct experiments to gain a realistic understanding of the complex environmental problems in industry, environmental management and the conservation of natural resources. They work with statistics and other raw data to create reports.

But in other biology/Science focuses on human cells and structure, functions, growth, origin, evolution, distribution and classification of all living things. It also deals with mechanisms around us.  

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11
