Since angles A and B are supplementary, the measure of angle B is equal to the difference of 180° and 135°, or 45°. The sum of the angles, formed by the perpendicular rays is 360°, thus the curved arrow represents an angle measure that is equal to the difference of 360° and 90°, or 270°. Thus, the area may be written as A=1/2(11)(6), or A = 33. The area of a triangle may be found by using the formula, A=1/2 bh, where b represents the base and hrepresents the height. Substituting 8 for d gives C=8π, where C is approximately 25.13. The vertex is the point, formed by the two rays of an angle. What is the measure of angle B in the following figure if angle A measures 135°? What is the measure of the solid line angle depicted by the following figure?ĥ. What is the area of the triangle below?Ĥ. Radius the distance or line segment from the center of a circle to any point on the circle. If a circle has the diameter of 8, what is the circumference?ģ. Unit 8: Circle Geometry Grade 9 Math Introduction: Definitions Diameter the distance across a circle, measured through its center or the line segment that joins two points on the circle and passes through the center. If the area of the shaded sector is 1.57 m 2, then calculate the size of ACB, to the nearest. Chapter 10 Review ( Answers) Biggest Circle Question Answers Chapter 11.
