Answer:
1.The degree measure of a major arcIf only the base and hypotenuse of a right triangle are given, then before finding the area of the triangle, we first need to find the height using the Pythagoras theorem. Then we can use the formula 1/2 × base x height to find its area. height = √[(hypotenuse)2 - (base)2] = √(52 - 42) = √9 = 3 cm. is 360° minus the degree measure of the minor arc that has the same endpoints as the major arc. The following theorems about arcs and central angles are easily proven.
2.In mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180° (equivalently, π radians, or a half-turn).
3.Square Area = a2 a = length of side
4.In other words, the area of a rectangle is the product of its length and width. That is, A = l x w where l is the length and w is the width of the rectangle. For example, the area of a rectangle of length 35 m and width 25 m is 35 times 25 or 875 square meters.
5.If only the base and hypotenuse of a right triangle are given, then before finding the area of the triangle, we first need to find the height using the Pythagoras theorem. Then we can use the formula 1/2 × base x height to find its area. height = √[(hypotenuse)2 - (base)2] = √(52 - 42) = √9 = 3 cm
