A student adds two displacement vectors that have the magnitudes of 15.0 m and 5.0 m. What is the range of possible answers for the magnitude of the resultant vector?

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

actually, no it isn't. when i was in junior high school, it was a blast. considering that it was a pre international baccalaureate school.
