Answer:
a) ∠ABC = 54°
a) ∠ABC = 43°
Step-by-step explanation:
<u>Trigonometric ratios</u>
where:
- is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
<u>Part (a)</u>
Use the cos trig ratio to find an expression for the measure of BD:
Use the cos trig ratio and the found length of BD to find angle ABD:
Therefore:
<u>Part (b)</u>
Use the tan trig ratio to find angle CAD:
Therefore:
∠ABC = ∠ABD
Interior angles of a triangle sum to 180°
Answer: 2 and a half slices
Step-by-step explanation: 5/2 is 2.5
Answer:
no because thats an obtuse angle and there has to be an acute triangle to from a triangle so no
Step-by-step explanation:
Answer:
1) a body of air with horizontally uniform temperature, humidity, and pressure.
2) the foremost part or surface of anything. the part or side of anything that faces forward: the front of a jacket.
3) A cold front is often associated with showers and thunderstorms. As it advances, often quite rapidly (50 to 65 km [30 to 40 miles] per hour), the cold air, which is relatively dense, undercuts the displaced warm air, forcing it to rise.
4) Cold Fronts. When a cold front passes through, the weather becomes significantly colder and drier. (It isn't uncommon for air temperatures to drop 10 degrees Fahrenheit or more within an hour of a cold frontal passage.) The weather map symbol for a cold front is a blue curved line with blue triangles.
5) When a cold front passes through, temperatures can drop more than 15 degrees within the first hour. Symbolically, a cold front is represented by a solid line with triangles along the front pointing towards the warmer air and in the direction of movement.
