Practice A Problems, Lesson 9.4 practice a geometry answers
| Problem | Solution |
|---|---|
Find the measure of angle B in the triangle below:  |
The sum of the angles in a triangle is 180 degrees. We know that angle A is 60 degrees and angle C is 70 degrees. Therefore, angle B must be 180- 60 – 70 = 50 degrees. |
Find the area of the triangle below:  |
The area of a triangle is given by the formula A = (1/2)- base – height. In this case, the base is 10 cm and the height is 8 cm. Therefore, the area of the triangle is A = (1/2) – 10 cm – 8 cm = 40 square cm. |
Find the circumference of the circle below:  |
The circumference of a circle is given by the formula C = 2πr. In this case, the radius is 5 cm. Therefore, the circumference of the circle is C = 2π- 5 cm = 10π cm. |
