Question 4 - Exponential, Logarithmic, Trigonometric & Hyperbolic Functions (c) A building site has the shape of an irregular quadrilateral as shown in the diagram
below (not drawn to scale). It has been decided to enclose the whole site by
building a wall around it, and divide the site into two plots by building a wall from B
to D.
152 m

740
390
449
138 m
Using trigonometric methods, determine the total length of the wall that needs to be
constructed, giving your final answer to 3 significant figures.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)

step-by-step explanation:

y= -2x+4, have a great day

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
