Answer:
x = 70
Step-by-step explanation:
Since the lines are perpendicular then ∠ AED = 90°, thus
x + 20 = 90 ( subtract 20 from both sides )
x = 70
Answer:
The solutions are:
x=2
x=−5
Explanation:
2x2+3x−10=0
hope this helps (:
Step-by-step explanation:
The complete question in the attached figure
we know that
sin40° = opposite side / hypotenuse
opposite side =AC
hypotenuse = AB-------> 10 in
so
sin 40=AC/AB---------> AC=AB*sin 40-------> AC=10*sin 40
the answer is
AC=10*sin 40
