4 lines are shown. 3 lines intersect and extend from one point forming 2 angles. The top angle is labeled 1 and the bottom angle is labeled 2. A fourth line intersects all 3 lines. When it intersects the middle line, it forms 4 angles. Clockwise, from the top, the angles are 3, 6, 5, 4. When it intersects the third line, it forms 4 angles. Clockwise, from the top left, the angles are 7, 8, blank, blank. Which angle pairs are supplementary? Check all that apply.
∠1 and ∠2
∠4 and ∠3
∠4 and ∠5
∠7 and ∠5
∠3 and ∠6

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

the f

last graph i believe

step-by-step explanation:

worked it out i believe

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

what level of math? also i don't need to be paid if i can you.
