HOW TO FIND 30 AND 60 DEGREES FOR SIN,COS AND TAN using one of the triangle I.e right angled triangle opp square= hyp square - adj square opp square = 2^2 - 1^2 opp square = 4 - 1=3 opp = root 3. Then... sin30 degree = 1/2 = 0.5 cos30 degree = root 3/2 = 0.8660 tan30 degree = sin30 degree/ cos30 degree = 0.5/0.8660= root 3/3 or 0.5774. sin60 degree = root 3/2= 0.8660 cos60 degree = 1/2= 0.5 tan60 degree = 0.8660/0.5 = root 3/1= root 3

Bearing and distance- City A is 300km due east of city B, city C is 200km on a bearing of 123degress from city B. How far is it from C to A... Solution Using the cosine rule formula a^2= b^2+c^2-2bccosA So therefore, b^2=a^2+c^2-2acCosB b(squared) = 200squared+300squared-2(200*300)cos33 = 40000+90,000-120,000cos33 =130,000-100640.47 =29359.53 b= square root of 29359.53 b=171.34...

Good day Maths geniuses,Todayi wil tutoring on how to find the square root of a Number.. HOW TO FIND THE SQUARE ROOT OF A DIGIT THAT HAS A PERFECT SQUARE Numbers that has a perfect square are numbers that their square root is a whole number without decimal or remainder.. All you need to solve this is your book,biro and your understanding...Below are the steps to take : 1. Subtract odd numbers starting from 1 from the number you want to look for it's square root till you get 0. 2 . Count the numbers of odd numbers you used and that's the square root of the number.That's all E.g Find the square root of 9 solution 9 - 1=8 , 8-3=5 and 5-5=0. That's all...Now,how many old numbers did i use to subtract..3 right.1,3,and 5 which means the square root 9 is 3
