In the figure below, CD bisects m∠ACB, AB=BC, m∠BEC=90°, and m∠DCE=42°. Find the measure of ∠A.
vesna_86 [32]

Answer:  ∠A= 24\textdegree

Step-by-step explanation:

Since we have given that

CD bisects m∠ACB,

⇒  m∠ACD= m∠DCB =x (say)

And, AB=BC, m∠BEC=90°, and m∠DCE=42°

So,

m∠CAD=m∠ACD

In ΔDCE,

\angle DCE+\angle CED+\angle CDE=180\textdegree\\\\(\text{Sum of anlges in triangle is }180\textdegree)\\\\42\textdegree+90\textdegree+\angle CDE=180\textdegree\\\\132\textdegree+\angle CDE=180\textdegree\\\\\angle CDE=180\textdegree-132\textdegree\\\\+\angle CDE=48\textdegree

Now, in  ΔACD,

x+x=48\textdegree\\\\2x=48\textdegree\\\\\text{( Sum of interior anlges is equal to exterior angles )}\\\\x=\frac{48}{2}\\\\x=24\textdegree

Hence , ∠A= 24\textdegree

Y and x vary directly. If the constant of variation is 1/2, then what is the value of y when x= -6
san4es73 [151]

If x=-6, then y=-3

Further explanation:

Direct proportion means that if a quanitity increases the other quantity also increases and vice versa

The direct proportion is written as:

If y and x vary directly then

y∝x

y=kx

where k is the proportionality constant

If k=1/2 then the expression will be:

y=\frac{1}{2}x\\Putting\ x=-6\\y=\frac{1}{2}* (-6)\\y=-3

If x=-6, then y=-3
