Answer:

Step-by-step explanation:
Notice that angles <1 and <3 are opposed by the vertex, which makes them of equal measure, therefore, <1 = 47 degrees.
Notice as well that angles <1 and <2 combine into a straight line, therefore, they are supplementary angles whose addition gives 180 degrees then we can find the value of angle <2 via:

And finally, angle <4 is opposite through the vertex to angle <2, and therefore they must have the same measure. So, <4 = 133 degrees.
Interior means inside and exterior means outside. So all that applies are 5 and 2. Mark brainest plz
It always helps to draw a picture. Given the information, Segment OF is the center line that is bisecting this angle.
Since it's bisecting (cutting in half)... we can simply set the two angles equal to each other.
y+30=3y-50
-2y+30=-50
-2y=-80
y = 40
C)40.
Answer:
D = -1, -1, 2, 5
R = 0, 2, 3, 7
✅It is NOT A FUNCTION
Step-by-step explanation:
D (Domain) = input values (x-values)
D = -1, -1, 2, 5
R (Range) = output values
R = 0, 2, 3, 7
✅It is not a function because an x-value, -1, has two different y-values, 7 and 2, assigned to it.
z equals -1 because 8 time negative one equals negative 8 plus 8 equals 0
