We have the formula tan(a+b)= (tana+tanb): (1-tana x tanb)
And now we have a=80, b=70 and
(tan80+tan70): (1-tan80 x tan70)= tan(80+70)= tan150
If you write 70 for 70°, we have tan150°=1/√3

Answer:
g(x) = -3*abs(x-1) + 3
Step-by-step explanation:
The graph got shifted over 1, so:
abs(x-1)
Flipped over x-axis:
-abs(x-1)
Scaled by a factor of 3, I just check the slope:
-3*abs(x-1)
Then finally shifted up 3:
-3*abs(x-1) + 3
answer a)
soln,
or, 4x + 84 = 180° [being co-interrior angle]
or, 4x = 180 - 84
or, 4x = 96
or, x = 96/4
x = 24
answer b)
soln,
or, 2x + 5 = 135° [being corresponding angle]
or, 2x = 135 - 5
or,2x = 130
or, x = 130/2
x = 65°
