PLEASE HELP ME WITH THIS QUESTION FOR MATH

∠MON = 130º

Step-by-step explanation:

∠LON = ∠LOM + ∠MON

∠LON = 180º

180 = (4x + 30) + (8x+ 90)

combine like terms

180 = 12 x + 120

60 = 12x

x = 5

plug x into equations.

∠MON = 8(5) + 90

∠MON = 40 + 90

∠MON = 130º

check work:

∠LOM = 4(5) + 30

∠LOM = 20 + 30

∠LOM = 50

∠LON = ∠LOM + ∠MON

180 = 50 + 130

A..

Step-by-step explanation:

We are given that a triangle on a coordinate plane is translated according to the rule T-3,5(x,y)

Here -3 means we move 3 units  towards right on x-axis.

5(x,y) means we move 5 unit upward on y-axis.

Therefore , the translation

x coordinate  change into x-3 and y coordinate change into y+5

The translation .

The new coordinates is .

Hence, the another way to write the given rule is .

Therefore, option A is correct.
