Given:
a ladder with three steps.
top step is 45° angle.
45° / 3 steps = 15°
So, top step is 45°. Middle step is 30°. Bottom step is 15°. Ground is 0°
The photographer would shout on the bottom step at an angle of 15°.
Answer:
The perimeter is 27 km
The area is 21 km^2
Step-by-step explanation:
The perimeter of a triangle will just be all of the sides added up.
12 + 9 + 6 = 27 km
The area of a triangle is:
A = 1/2 * base * height
The base is 6 km, and the height is 7 km. Substituting the values in and solving, we get:
A = 1/2 * 6 * 7
A = 3 * 7
A = 21 km^2
Answer:yes

Answer:
One batch of bread requires 1 1/3 cups of flour
<h3>Step by step equations:</h3>
6 2/3= 20/3
20/3 ÷ 5/1 = 20/3 x 1/5
20/3 x 1/5 = 20/15
20/15 simplified is 1 1/3
