Answer:
x = 50
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 2 given angles in the lower triangle and subtract from 180 to find the third angle
third angle = 180° - (65 + 65)° = 180° - 130° = 50°
x = third angle = 50 ( vertical angles )
Factor out cosx: cosx(sinx-2)=0
cosx=0 or sinx-2=0
cosx=0 or sinx=2
the largest value of sinx is 1, sinx will never be 2, so cosx=0, x=π/2 or 3π/2 are the two answers.
P = 2L + 2W
P = 2(2x) + 2(4x + 3)
P = 4x + 8x + 6
P = 12x + 6
The correct response would be D. 12x + 6.
