Fraction form 41/400
decimal form .1025
-4y-11 that the answer hope it helps
Line 1 is in q1 and line 2 is q4
To find the inverse we swap y and x and solve for y:
x = 9y + 15
x - 15 = 9y
y = (x-15)/9
Last choice
Remember that all the interior angles of a triangle add up to 180°.
The picture tells us two of the angles,

which is 40° and

which is also 40°.
Subtract the measurement of these two angles from 180° to find the measure of the third angle,

:
180° - 40° - 40° = 100°.
The measure of angle RST is 100°.

Answer: 100°
