Answer:
48 degrees
Step-by-step explanation:
Angle 2 is a right angle.
Right angles are 90 degrees.
A line is 180 degrees.
Angle 1, 5, and 2 form a line.
180-90=90
That means that Angles 1 and 5 add up to 90 degrees.
We know that Angle 3 is 42 degrees.
Angle 3 and 5 are Vertical angles.
Vertical angles are always congruent.
This means that Angle 5 is also 42 degrees.
As we discussed earlier, Angles 1 and 5 are complementary. (Add up to 90 degrees)
42+x=90
Subtract 42 from both sides.
x=48
m<1=48
<span>4x+7y=51
Plug in </span><span>y=5::
4x+7(5)=51
Simplify:
4x+35=51
</span>
<span>4x+35-35=51-35
4x=16 (÷4)
x=4
Done :)

It is given in the question that QS bisects angle PQR .
And since, QS bisects angle PQR, therefore
![[tex]m \angle PQS = m \angle RQS](https://tex.z-dn.net/?f=%5Btex%5Dm%20%5Cangle%20PQS%20%3D%20m%20%5Cangle%20RQS)
[/tex]
Substituting the values of angle PQS and angle RQS, we will get
PQR is twice of angle PQS. Therefore angle PQR is
