Answer:
x=9
Step-by-step explanation:
-5 square root x =-2+3
5x=4x^2 −12x+9
Simplify 25x-4{x}^{2}+12x-925x−4x 2 +12x−9 to 37x-4{x}^{2}-937x−4x 2-9
then...
(4x−1)(x−9)=0
x=1/4,9
-drop 1/4
x=9
Answer:
x = π/6, 5π/6
Step-by-step explanation:
4 sin² x − 4 sin x + 1 = 0
(2 sin x − 1)² = 0
sin x = ½
x = π/6, 5π/6
We have
angle 1=

see the attached picture to better understand the problem
we know that
<span>Vertical angles are congruent
</span>

<span>
and
adjacent angles are supplementary
</span>

<span>
if the measure of one of the angles is </span>

degrees and straight lines equal

<span> degrees you have to
subtract </span>

from

so

therefore


the answer is
the measures of the other three angles are
Answer: the answer is 40
