Answer: The height of the taller building is 320 meters
Step-by-step explanation: Please refer to the attached picture for details.
The two buildings have been illustrated in the picture attached as points A and E. The distance between them is line BE which is 24.5 m.
The height of the shorter building which is ED and also equal to BC is given as 40 m.
Looking up at the top of the taller building which is point A an observer forms an angle of elevation of 85 degrees which is angle AEB.
We shall begin by solving for distance AB in triangle ABE. The line AB also marked as e is the opposite, while the line BE which is 24.5 is the adjacent. Hence;
Tan 85 = Opposite/Adjacent
Tan 85 = e/24.5
Tan 85 * 24.5 = e
11.43 x 24.5 = e
280.035 = e
e ≈ 280
Our result shows that from the top of building E, building A measures approximately 280 metres. Having in mind that the taller building (line AC) includes the height (line BC) of the shorter building, building A now becomes,
AC = Line BC + Line AB (that is e)
AC = 40 + 280
C = 320 meters
Therefore the height of the taller building is 320 meters
2.the y-intercept of the equation is zero
3.it is possible that the line on the graph is horizontal
So matrix which show equation 4x+2y=4 is .
Given that we have an equation that is 4x+2y=4
So equation is a statement that the values of two mathematical expressions are equal (indicated by the sign =).
So in order to write this equation in matrix form we have to write it into augmented matrix
So augmented matrix is a matrix whose elements are the coefficients of a set of simultaneous linear equations with the constant terms of the equations entered in an added column.
Therefore the matrix will be:
