Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
There is a cyclic quadrilateral.
As we know that "Sum of opposite angles in a cyclic quadrilateral is supplementary.":
so, it becomes,
Hence, the measure of ∠1 = 94°
Therefore, Third option is correct.
<span>If you would like to know in which step did the student first make
an error, you can find this using the following steps:
y = 4 - 2z
4y = 2 - 4z
________________
-4(y) = -4(4 - 2z)
</span>4y = 2 - 4z<span>
________________
-4y = -16 + 8z ... Step 2
</span><span>4y = 2 - 4z</span><span>
________________
0 = -16 + 8z + 2 - 4z</span>
<span>16 - 2 = 4z</span>
<span>14 = 4z</span>
<span>z = 14/4 = 7/2</span>
<span>
The correct result would be: Student made an error in Step 2.</span>
we are given
We will simplify left side and make it equal to right side
Left side:
we can use trigonometric identity
we can replace it
we know that
csc=1/sin and sec=1/cos
so, we can replace it
and we get
now, we know that
tan =sin/cos
we can simplify it
and we get
we can also write it as
Right Side:
we can see that
left side = right side
so,
