Find angle measures and arc measures

Mathematics
1 answer:
Vlad1618 [11]3 years ago
3 0

Answer:

Step-by-step explanation:

a. We know that KH is a diameter of the circle and that along angles along it on either side adds up to 180° as it's a straight line.

-Therefore, we have that:

m\angle a+ \angle GaH=180\textdegree\\\\\\m\angle a=180-35\\\\=145\textdegree

Hence, the angle a is equal to 180°

b.We know that GJ is a diameter of the circle and that along angles along it on either side adds up to 180° as it's a straight line.

-Therefore, we have that:

m\angle b+\angle GaK=180\textdegree\\\\m\angle b=180\textdegree -145\textdegree\\\\\\\\=35\textdegree

Hence, the angle b is equal to 35°

Which function represents the graph of f(x)=|x+2| after it is translated 4 units to the right?
Kisachek [45]

Answer:

g(x)=|x-2|

Step-by-step explanation:

The vertex form of an absolute function is

g(x)=|x-h|+k            .... (1)

where, (h,k) is vertex.

The given function is

f(x)=|x+2|

The vertex of the function is (-2,0).

It is given that graph of f(x) is translated 4 units to the right. So, the vertex of the function after translation is (2,0).

Substitute h=2 and k=0 in function (1).

g(x)=|x-2|+0

g(x)=|x-2|

Therefore, the required function is g(x)=|x-2|.

Please help; I’m hopeless.
Yuliya22 [10]
Well, you have to find 2 of the same number that add together to make that middle number before the c. Then you have to multiply those 2 identical numbers together to find the value of c!——————————————————————So! For number 10, 7+7 is 14, so 7 and 7 are your two identical numbers.——————————————————————Then you have to multiply them to get c! 7•7=49, so 49 is c.——————————————————————I’ll do 11 for you as well, 12+12=24, and 12•12=144, so 144 is c.
