Answer:
26 inches
Step-by-step explanation:
We are given;
- An inscribed circle whose area is 407 square inches
- In this case, we need to know that an inscribed in a square touches the four sides of the triangle.
- Therefore, the diameter of the circle is equivalent to the side of the square.
We are given the area as 507 square inches
But;
Area of the circle = pi × r²
Thus we can get the radius of the circle;
Thus;
507 in² = 3 × r²
r² = (507 ÷ 3)
= 169
r =√169
= 13 inches
But, Diameter = 2 r
Thus; Diameter = 2 × 13
= 26 inches
But, in this case, diameter = side of the square
Therefore, the side of the square is 26 inches
Answer:
21 feet (20.977)
Step-by-step explanation:
1. Draw a picture, it makes it much easier. Draw a right triangle with the vertical labeled 25 and the horizontal labeled X, then label the angle adjacent to the horizontal and hypotenuse 40°
2. Use tangent because X is opposite of 40 and 25 is adjacent to angle 40. the equation would be Tan40/1 = X/25
3. You then cross multiply to get 25Tan(40) = X
4 You then plug it into a calculator and get the full answer of 20.97749078, but I always round up to either 20.98 or 21 feet, whatever your teacher allows
