The top and bottom length are 9 and 9 right? so multiply 9x2 which is 18cm. then to find the missing length, you already know that the length to your right is 6cm. and so will the one on your left will be 6cm, so multiply 6x2 and you get 12cm. add 18cm and 12cm and you get the answer 30cm. perimeter=30cm.
Answer:
3xpi/2 is 270 degree counter-clockwise from Ox
That time P(x,y) is (0,-1)
=> x= 0 and y = -1 as you can see in picture.
=> Cos 3pi/2 = x = 0
=> Sin 3pi/2 = y = -1

The missing angle of the given triangle is 59°.
What is vertically opposite angles?
Angles that are vertically opposed to one another are always equal to one another. A vertical angle and the angle to which it is next are also supplementary angles; that is, they sum up to 180 degrees. As an illustration, if two lines connect to form an angle, say X=45°, then the angle's opposite angle is also 45°.
Here consider angle with 31° and 49° triangle is 1. We know that sum of all angles in triangle is add upto 180°. Then,
⇒ 49°+31°+x = 180°
⇒ 80° + x= 180°
⇒x= 180°-80°=100°
Then unknown angle in triangle 1 ia 100°.
Now according to the vertically opposite angle theorem , opposite angles are equal to each other. Then ,
In triangle 2 angle is 100° and 21°. Then missing angle is,
⇒ 100°+21°+missing angle =180°
⇒Missing angle = 180°-100°-21°
⇒Missing angle = 59°
Therefore the answer is 59°.

You would say 1/48=28/x and solve the proportion to get an answer of 1344 inches, which is 112 feet.
In this case there will be 2 solutions to solve for in this equation, both will equal plus and minus the answer. Which is 14.
6(3x + 5) = +_ 14
The solutions will be the following :
(14/6 - 5)/3
(-14/6 - 5)/3.
