After it dried, which took about two hours, I sanded it flush with the wood using #120-grit sandpaper, then stained the entire shelf. You have to look closely to see the spot where the nail hole had been! Quick Tip: Always sand in the direction of the grain of the wood to avoid unsightly scratches.
Angle Sum Theorem. The Angle Sum Theorem gives an important result about triangles, which is used in many algebra and geometry problems. We give the proof below. Theorem: The sum of the measures of the interior angles of a triangle is 180 Â°. Given: Î X Y Z. Prove: m â  1 + m â  2 + m â  3 = 180 Â°
exists and is an alternate of . 180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees. 180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees. Minor edit?
