Answer:
D. 42
Step-by-step explanation:
Answer: 238.95 in²
because this is a regular pentagon
=> the area of the regular pentagon will be 5 times the area of the triangle in the picture.
we have: the area of the triangle is: (11,8.8,1)/2 = 47,79 (in²)
=> the area of the regular pentagon is 5. 47,79 = 238,95 (in²)
Step-by-step explanation:
Answer: 1/3
Step-by-step explanation:
- Two points on this graph are (40, 80) and (70, 90). These points can be used to find the slope.
- The formula for slope is (y2-y1)/(x2-x1).
- Plugging our numbers into the formula:
- (80-90)/(40-70) = (-10)/(-30) = 1/3
1 1/10
