Triangles have 180 degrees. Assuming angle N = angle ISP = angle S, angle P = angle SPI, and angle I = angle SIP; then we have: angle P = (x + 1), angle N = (4x + 13), and angle I = (2x + 35). The sum is then (x + 1) + (4x + 13) + (2x + 35) => (x + 4x + 2x) + ( 1 + 13 + 35) => 7x + 49 = 180 => x = (180 - 49)/7 => 131/7 = 18.7, So, n = 4(18.714) +13 = 87.856 degrees. Angle P = 18.714 + 1 = 19.714 degrees and angle SIP = 2 * 18.714 + 35 = 37.428 + 35 = 72.428 degrees. Now, the sum of the angles = 87.856 + 19.714 + 72.428 = 179.998 degrees. This checks, given the initial clarifications regarding the angle designations. The answer is then: angle n = 87.856 degrees. Not one of your choices I'm afraid. Look at my step-by-step method. Without the initial clarifications, angle n would just be angle n or 4x + 13, because you have only clearly defined angle P and angle SIP. Angle S is missing, so I set it to angle n.

Maybe if you explained what these angles are part of and how they are related to this object, then someone could try to help you.
