Answer:
<u>Area:</u> 10,000 yards
<u>Perimeter:</u> 410 yards
Step-by-step explanation:
<u>Area: To find area, multiply one side by the other</u>
80 * 125
10,000
Answer: 10,000 yards
<u>Perimeter: To find the perimeter, use the formula 2a + 2b </u>
2(80) + 2(125)
160 + 250
410
Answer: 410 yards
Answer:
x = 559.31 m
Step-by-step explanation:
Given in the question,
horizontal distance from airplane to the coral reef = 3172 m
outer angle of depression = 10°
inner angle of depression = 90 - 10
= 80°
It is a question of right angle triangle, we will use trigonometry identity to solve the question
<h3>Tan(80) = base / height</h3>
Tan(80) = 3172 / x
x = 3172 / Tan(80)
x = 559.31 m
Answer:
Step-by-step explanation:
General equation for a circle (x - a)² + (y - b)² = r² with (a,b) represents the center, (x,y) represents one of the points lie on the circle, and r represents the radius Determine r² by substituting the points into the general equation (x - a)² + (y - b)² = r² (5 - (-1))² + (-4 - 2)² = r² (5 + 1)² + (-6)² = r² 6² + 36 = r² 36 + 36 = r² 72 = r² Determine the equation of the circle (x - a)² + (y - b)² = r² (x - (-1))² + (y - 2)² = 72 (x + 1)² + (y - 2)² = 72 (This is the equation of the circle)
Answer:
6 ft = <u>2</u> yd
6 ft = 6 x 1 ft
= 6 x <u>2</u><u> </u>yd
= <u>1</u><u>2</u><u> </u>yd
