No, if you have the length of all 3 sides, the 3 angles are fixed You can find the angles of any shape of triangle using the cosine rule, if you know all three sides For a 345 triangle, you know one angle is right angle, so you can save time and use the definitions of sine and cosine instead of using the full cosine rule Any triangle with sides of 3, 4 and 5 feet will have a 90 degree angle opposite the 5 foot side If a larger triangle is needed to increase accuracy of very large structures, any multiple of 345 could be used (such as a 6810 foot triangle or a foot triangle)45 210 Section 23 significant figures and solving right triangles Definition The number of significant digits (or figures) in a number is found by counting all the digits from left to right beginning with the first nonzero digit on the left When no decimal point is present,
