I'm not sure how to answer this question:
"ABC is a right-angled triangle.
AC = 14cm
Angle C = 90°
Size of angle B : size of angle A = 3 : 2

Work out the length of AB.
Give your answer correct of 3 significant figures"

How do I solve this?
I decided it is about time I portioned off a part of my yard and make a marshmallow garden. The area I have decided to portion off is created by combining two shapes: A rectangle and an equilateral triangle, with the equilateral triangle directly on top of the rectangle (think of those terrible houses you used to draw as children). I have 900 meters of fencing to use, and I know the length of the rectangular area needs to be 1.5 times the width. If the base of the triangle is the exact same in measure to the length of the rectangle, what are the dimensions of all sides of this portioned area?

Name the intersection of PR and HR
Which of the following statements is/are true?
A. Suppose a sphere has a diameter of 10 cm. Suppose the height of a closed right circular cylinderis double its radius, and that its radius is the same as the radius of the sphere. The ratio of the surface area of the sphere to that of the cylinder is 2 : 3.
B. If the diameter and height of a right circular cone are equal then the lateral surface area of the cone is √ 5πr2 , where the radius is r. (Note: Lateral surface area of cone is the area of the sides only.)
C. If the diagonals of a quadrilateral intersect at right angles the quadrilateral must be a square or a rhombus or a kite.
1. Only A 2. Only B 3. Only C
4. Only A and C 5. A, B and C
