This is the concept of trigonometry, to get the possible length of side a we use the sine rule which states that: a/sin A=b/sin B=c/sin B where; a,b and c are the sides A,B and C are the angles thus the value of A could be as follows; assuming the triangle is an isosceles triangle, the base angles will be: (180-40)/2=70 thus; 15/sin 70=a/sin 40 a=(15sin40)/sin70 a=10.26 inches thus the possible size of a=10.26 inches
Answer:The slant height of the top is 5 m, and the height of the cylinder is 9 m. Find the distance between P and Q, to the nearest cm. 0 height of small triangle.
