Answer:
D
Step-by-step explanation:
f(x ) =
inverse ----> f(x) = y = x
x = - 1
y = ±
For this equation I used the fact that S and U are congruent (because Line ur and rs are equal and lines UT and TS are equal. All the interior angles need to add to 360 degrees. U+R+S = 340 so T has to equal 20 degrees.
Answer:
-48
Step-by-step explanation:
Answer:
angle D equal to 3 X + 20 + 7 x minus 3 x
=90 degree equal to x minus 3 X + 20
7 X equal to 70 X equal to 10
