13x - 23 - 45 = 7x + 12

Explain to a new student how a reflection across the y-axis changes the coordinates of the original point.

RSB [31]

If you were to have (3,2) and find the reflection of the y axis, it would turn y into a negative, making it (3,-2).

Math... find angle x...

choli [55]

Value of x is 76°

<u> </u><u>Step-by-step explanation:</u>

Given :- ∠JIH = 107°

and, JDI = 31°

To find :- value of x

solution:- ∠JIH + ∠JID =180° (the sum of angles on a line are supplementary)

∠JID = 180° - 107°

∠JID = 73°

Now in ΔJID

∠JID = 73° and ∠JDI = 31°

by angle some property of Δ

so, ∠JDI + ∠JID + ∠DJI = 180°

= 31° + 73° + ∠DJI = 180°

= 104° + ∠DJI = 180°

∠DJI = 180° - 104°

∠DJI = 76°

now, ∠DJI = ∠AJF = ∠X

so, x = 76°

hence value of x is 76°
