9514 1404 393

Answer:

  a.  -165°

Step-by-step explanation:

The line from A through P to A' is almost straight, so an angle near 180° is indicated. In the figure, A' is to the left of the line AP, so clockwise rotation is indicated.

The rotation angle is a negative angle near 180°. The best choice is ...

  a.  -165°

17. Classify Each Angle Pair then find the value of X
IRISSAK [1]

<u>Given</u> -

  • If l || m, m∠1 = (13x + 24)°, and m∠2 = (5x-6)°,

<u>To find</u> -

  • m∠2.

<u>Concept</u> -

Whenever two parallel lines are cut by a transversal, an interesting relationship exists between the two interior angles on the same side of the transversal. These two interior angles are supplementary angles. Hence, according to the figure l and m are two parallel lines and t is the transversal intersecting them then ∠1 + ∠2 = 180°.

<u>Solution</u> -

\rightarrow\sf{(13x+24)^{ \circ}+(5x-6)^{ \circ}=180^{ \circ}}

\rightarrow\sf{13x+5x+24-6=180}

\rightarrow\sf{18x+18=180}

\rightarrow\sf{18x+18=180}

\rightarrow\sf{18(x+1)=180}

\rightarrow\sf{x+1=\frac{180}{18}}

\rightarrow\sf{x+1=10}

\rightarrow\sf{x=10-1}

\rightarrow\boxed{\bf{x=9}}

m∠2 = (5x-6)° = {5(9) - 6}° = {45 - 6}°= 39°

Henceforth, m∠2 = 39°

M/PQR if mzPQR = (10x 7), m/RQT = 5x°, and m/PQT=(4x+6).
vodomira [7]

The measure of ∠PQR will be 123° .

Interior Angles of an Angle:

An interior of an angle is a line that separates an angle into two angles. If BD is the interior of an angle ABC then the measure of the angle ABC is the sum of both the angles.

∠ABC = ∠ABD +∠DBC

We can divide an angle into many interior parts or angles.

If we have an angle and there are many interiors that divides the angle into many parts than the sum of all the interior angles is equal to the measure of the original angle.

If we have D and E are the two interiors of ∠ABC then ,

∠ABC =∠ABD + ∠DBE + ∠EBC

Given that point T is in the interior of ∠PQR  and ∠PQR =10x-7

                                                                                 ∠RQT =  5x°

                                                                              ∠PQT=(4x+6) .

Since T is the interior of  ∠PQR ,

∠PQR =      ∠PQT + ∠RQT

10x-7 = 4x + 6 + 5x

10x-7 = 9x + 6

x = 13°

So from the equation(1)-

∠PQR = 10(13) - 7

∠PQR = 123°

So ∠PQR = 123° .
