Step-by-step explanation:
Therefore,
(x+20) + (x-10) + (2x-30) = 180° (Sum of interior angles of a triangle)
Or, x+x+2x+20-10-30 = 180°
Or, 4x-20 = 180°
Or, 4x= 180+20
Or, 4x= 200°
Or, x= 200°/4
Therefore, x= 50°
So,
(x+20)
= 50+20
=70°
(x-10)
= 50-10
40°
(2x-30)
= 2×50-30
=100-30
=70°
Hope it helped, If it did, please mark it as the brainliest answer :)
The domain of the function is the set of all the values of x that would allow the function to have real values. Since the radicand is x - 3, the value of x cannot be less than 3 because that would make the value of sqrt (x - 3) an imaginary number. Thus, the domain should be all numbers GREATER than or equal to 3.

Answer:
3
Step-by-step explanation:
Y >/= -1/2x + 2
Y > 2x - 3
You get the >, <, and = by looking at the shading and line.
A dotted line is just > or <.
A solid line is >/= or </=.
You get the y-intercept, or the +2 or -3 by looking at the point on the y-axis.
