tell whether the angles are adjacent or vertical then find the value of x. can someone help me please i need all the answers
dmitriy555 [2]

Answer:

3. adjacent; 49
4. adjacent; 71

5. verticle; 41

6. adjacent; 14

Step-by-step explanation:

ok basically if the angles are next to each other, then they're adjacent and if they're across from eachother they're verticle.

to find 3:

set both equations equal to each other and solve because verticle angles are equal

to find 4:

add the 2 equations together and set it equal to 180 because adjacent angles add up to equal either a complementary angle or supplementary depending on the problem

Find the area of a circle with diameter,
DIA [1.3K]

Answer:

A = 25pi m^2

Step-by-step explanation:

We know the diameter, we need the radius

r = d/2

r = 10/2 = 5

The area of a circle is given by

A = pi r^2

A = pi (5)^2

A = 25pi m^2

I need geometry help
fiasKO [112]
I believe you can do x + 2.7 = 16.

I took geometry last year and those arrow things are basically saying the line is the same if they have the same number of arrows. Using that logic, you can equal them out and find X.

Your answer is 16 - 2.7
