Answer:
The value of DC is 66.34.
Step-by-step explanation:
The triangles ABC and DCA are right angled triangles.
The straight line AC is a bisector for angles C and A.
The measure of ∠C is 30°.
Then the measure of angles BCA and ACD will be 15° each.
The measure of angle DAB is 150°.
Then the measure of angles DAC and BAC will be 75° each.
Now consider the right angled triangle ABC.
The measure of side AC is:
Consider the right angled triangle DCA.
The angle DAC measure 75°.
Using the trigonometric identities compute the value of Perpendicular DC as follows:
Thus, the value of DC is 66.34.
Answer:
Unit of measure
Step-by-step explanation:
Unit of measure
When we construct any type of graph the unit of measure needs to be present, becuase the numbers without units are just numbers and with just the numbers we can't have physical interpretation of the situation.
For this reason is importatn to include the units of meausre with the plots since with that we have a point of reference for the variables used.
And satisfy the condition "A standard of measure for a physical quantity and is included as part of the x and y axes labels on a line graph."
Answer:
10x2y3 -4xy2
Step-by-step explanation:
Just take the like terms and separate them-
1) 4x2y3 - (-7x2y3)= 10x2y3
2)2xy2 - 6xy2= -4xy
3)-2y - (-2y)= 0y
Hope this helps :)
The other endpoint (x,y)
(X+18)/2 = 16 then x=14
(Y-18)/2 = -16 then y=-14
