Based on the data provided, Anthony will be safe because Anthony's ladder will make a 75. 522 degree angle.
<h3>What is the height of the wall?</h3>
The height of the wall is determined using trigonometric ratios.
Since the ladder must be within 1 degree of 76 degrees to be safe, we assume the maximum angle to be 77°.
Length of the ladder = 10 m
The ladder, the wall of building and the floor form a right-angled triangle.
Height of wall = 10 × sin 77°
Height of wall = 9.74 m
If Anthony places the ladder 2. 5 feet from the base of the building, angle A, it will make with the floor is calculatedas follows:
Cos A = 2.5/10
Cos A = 0.25
A = 75.522°
Therefore, Anthony will be safe because Anthony's ladder will make a 75. 522 degree angle.

Answer:
A digestive system uses enzymes to break down your food. The walls of the intestines absorb nutrients and vitamins, while the unused food gets processed to be removed from your body (Feces).

Answer:
During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Explanation:
The energy for photosynthesis comes from light. Light energy is converted to chemical energy by chlorophyll. There are two sets of reactions, light dependent and light independent. The process mostly takes place in the chloroplasts of plant leaf mesophyll cells. Photosynthesis is the process where a plants uses the sun’s energy to turn light into chlorophyll. Plants produce oxygen during this process and utilize carbon dioxide. Photosynthesis is the single most important chemical process on the earth. Almost all plants needs the sun in order to survive Photosynthesis is the most important chemical process on earth – it provides food and energy for all living creatures who eat the plants that rely on this process to produce their food (glucose). · More than half (70%) of the world’s oxygen is produced by phytoplankton photosynthesis in the world’s oceans.
