Answer:
x = 20
Step-by-step explanation:
Intersecting Chords Theorem: ab = cd
Step 1: Label our variables
<em>a</em> = x
<em>b</em> = x - 11
<em>c</em> = x - 8
<em>d</em> = x - 5
Step 2: Plug into theorem
x(x - 11) = (x - 5)(x - 8)
Step 3: Solve for <em>x</em>
x² - 11x = x² - 8x - 5x + 40
x² - 11x = x² - 13x + 40
-11x = -13x + 40
2x = 40
x = 20
Answer:
x=180
Step-by-step explanation:
6/30 = x/900
I think it’s C
Sorry if it’s wrong
Angles 2 and 6 are corresponding angles.
When parallel lines are cut by a transversal, corresponding angles are congruent, so angles 2 and 6 are congruent.
m<2 = m<6 = 64 deg.
Angles 5 and 6 are a linear pair, so they are supplementary, and their measures add to 180 deg.
m<5 + m<6 = 180
m<5 + 64 = 180
m<5 = 180 - 64
m<5 = 116
Answer: m<5 = 116 deg.
