Help pls is this a non-linear or linear???

Virtual school sucks xc (05.01)allison has a poster that is 15 in by 18 in. what will the dimensions of the poster be if she scales it down by a factor of one-third ? 15 in by 18 in 45 in by 54 in 2.5 in by 2 in 5 in by 6 in question 2(multiple choice worth 5 points) (05.02)how many triangles can be made if two sides are 4 inches and the angle between them is 90°? 1 2 more than 2 none question 3 (true/false worth 5 points) (05.02)a triangle can be formed with side lengths 2 in, 3 in, and 6 in. true false question 4(multiple choice worth 5 points) (05.02)find the measure of angle x in the figure below: two triangles are shown such that one triangle is inverted and they share a common vertex. the lower triangle has two angles at the base. the lower left angle is marked as 55 degrees. the lower right angle is marked as 30 degrees. the angle at the vertex of the inverted triangle at the top is marked as x degrees. 95° 55° 30° 85° question 5 (essay worth 5 points) (05.01)a scale drawing of a living room is shown below. the scale is 1 : 40. a rectangle is shown. the length of the rectangle is labeled 6 inches. the width of the rectangle is labeled 4 inches. show your work to determine the area of the room in square feet. question 6 (essay worth 5 points) (05.02)in the figure below, angle y and angle x form vertical angles. angle y forms a straight line with the 80° angle and the 60° angle. a straight line is shown and is marked with three angles. the first angle measures 80 degrees. the second angle measures 60 degrees. the third angle is labeled y. the line between the 60 degree angle and angle y extends below the straight line. the angle formed is labeled angle x. write and solve an equation to determine the measure of angle x.
