You find the area of a triangle by using 1/2*b*h where b is the base and h is the height. since we already know the area is 20 and the height is for you plus them in so the problem would be 20= 1/2 (b) (4) then you multiply what you know together to get 20= 2b and then isolate the b by dividing both sides by two so the base should be 10 m

HERE IS YOUR ANSWER
Step-by-step explanation:
Use the mirror equation:
1/di + 1/do = 1/f
where di = -10 cm and f = +15 cm. (Note that di is negative if the image is virtual.)
Substitute and solve for do.
1/do + 1/(-10 cm) = 1/(15 cm)
1/do = 1/(15 cm) - 1/(-10 cm) = 5/(30 cm)
do = 6 cm

Answer:
Area of the field that the cow graze = 235.71 sq. ft
Step-by-step explanation:
Area of the field that the cow graze = (120 / 360) * πr²
= (1/3) * (22/7) * 15 * 15
= (22 * 5 * 15) / 7 = 1650 /7
= 235.71 sq. ft
