ANSWER:
x = 60°
STEP-BY-STEP EXPLANATION:
Let's first establish that the angle sum of a triangle is equivalent to 180°.
Angle sum of triangle = 180°
As well as this, the angle where the blue ( x ) is added on the diagram is equivalent to ( x ) as they are vertically opposite angles. Verically opposite angles are equivalent to each other.
From this, we can establish the following:
( x ) + ( 50 ) + ( x + 10 ) = 180°
Now we will solve this equation to obtain the value of ( x ).
2x + 60 = 180
2x = 180 - 60
2x = 120
x = 120 / 2
x = 60°
Answer:
-43
Step-by-step explanation:
just plug in -9 for x and solve
g(-9)=4(-9)-7
=-43
Answer:
n = (-4)
Step-by-step explanation:
Firstly expand the bracket
;2[3(1 - n) -2(1+n)]
;2[ 3 - 3n - 2 - 2n ]
;2[ -5n + 1 ]
; -10n + 2
then go back to the question and substitute the bracket with the simplified form above,
; 7n - 10n + 2 = 14
; -3n = 14 - 2
; -3n = 12...then divide both sides by (-3)
;Hence... n = (-4)
