Answer:
150
Step-by-step explanation:
3 times 50 equal 150
Answer:
Step-by-step explanation:
From the given picture,
∠ABE = ∠DEF = 90° [Since, AB and DE are perpendicular to DE]
m∠ECA = m∠BFD [Given]
m∠ECA + m∠ACB = 180° [Liner pair of angles]
m∠BFD + m∠DFE = 180° [Liner pair of angles]
m∠ACB + m∠ECA = m∠BFD + m∠DFE [Transitive property]
m∠ACB = m∠DEF [Since, m∠ECA = m∠BFD]
Therefore, ΔABC ≅ ΔDEF [By AA property of similarity]

Answer:
The angle of elevation is approximately 
Step-by-step explanation:
Notice that the two pieces of information given: "400 ft away from a building", and building that is "850 ft tall", can be regarded as the two legs of a right angle triangle (see attached image).
Then the angle
that we are trying to find (the angle of elevation) can be found by using the arc-tangent function:

Answer:

Step-by-step explanation:
From the question, we are given;
- The equation y = 3x + 2
- A point (-1, -2)
We are required to determine the equation of a line parallel to the given line and passing through the point (-1, -2)
- We are going to determine the gradient of the line first; when an equation is written in the form of y = mx + c, where m is the gradient.
y = 3x + 2, m₁ = 3
- But, m₁ = m₂ for parallel lines
- Therefore, the gradient of the line in question, m₂ is 3
- With the gradient, m₂=3 , and a point (-1, -2) we can get its equation;
Taking another point (x, y)...
Then;


Therefore; the equation of the line is
