A group of Environmental Science team travel 20 miles to a field to conduct measurements and observations, due to floating the government improvise a rod for them, now they travel 8% less than usual. Calculate the number of miles they are traveling now?

They now travel 18.4 miles

Explanation:

Given

Required

Determine the new distance covered

First, we need to determine the reduced distance

This is calculated as thus:

Convert % to decimal

Now, the new distance can be calculated;

Hence; they now travel 18.4 miles

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
