Angles along a straight line equal 180. This means that the unmarked angle of the triangle is equal to (180-153)=27.
Angles in a triangle add to 180. This means:
(x-4)+(2x+10)+27=180
3x+33=180
3x=147
x=49
Answer:
From the given options, option D is the only choice that contains (w-5).
Step-by-step explanation:
Given the expression

Breaking the expression into groups

Factor out 'w' form w²+4w = w(w+4)
Factor out 'w' from -5w-20= -5(w+4)
so

Factor out common term: w+4

Thus, the factors are: (w+4) and (w-5)
Therefore, from the given options, option D is the only choice that contains (w-5).
Answer:
9
Step-by-step explanation:
The exterior angle is equal to the sum of the 2 opposite interior angles, therefore:
9x + 9 = 45 × 5x
4x = 36
x = 9
