Answers

1.When the piston is at its highest point in the cylinder (TDC), the cylinder volume is at its; B. largest

2.A complete run through all four stages of engine operation-intake, compression, power and exhaust is called an engine cycle

Explanation

The Top Dead Center (TDC) is a point when the piston of an engine is at the most top of its stroke. The TDC can be reached by the piston when on compression stroke and during the exhaust stroke. At TDC, the cylinder volume is at its largest since it will have more space covered.

An engine that has four strokes works through a complete rotation of the crack shaft which covers the intake, compression, power and exhaust stroke to complete a four cycle engine. One operating cycle is attained when the piston successfully makes two complete passes in the cylinder.

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
