The answer to the questions
Answer:
8 1/6 < x < 20.5.
Step-by-step explanation:
Use the Triangle Inequality Theorem which states that the sum of any 2 sides of a triangle is always greater that the third side.
So for triangle to be formed:
4x + 2x - 4 > 45
6x > 49
x > 8 1/6.
Also 2x - 4 + 45 > 4x
41 > 2x
2x < 41
x < 20.5.

In the given figure, it's an Isosceles triangle having two equal sides RP and RQ, therefore their opposite angles will be equal as well, that is ~
Angle P = Angle Q = 29°
Now, by Angle sum property of a triangle, we get ~
Therefore , value of x is 17°
supplementary angles measure 180°
Did you mean -21(-2-5)+(-14)+6(8-4.3) ?
If that, the answer is 155.2:)) im sorry if im wrong:((
