Triangle=94
Rectangle=864
Step-by-step explanation:
Triangle:
4*3=12, *2=24
6*5=30
6*3=16
4*6=24
24+24=48, +30=78, +16=94
Rectangle:
30*7=210, +210=420
30*6=180, +180=360
7*6=42, +42=84
420+360=780, +84=864
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.
