The answer is 12.3 inches
Answer:
E
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Consider the triangle on the left
3rd angle = 180° - 60° - 90° = 180° - 150° = 30°
the 3rd angle of the triangle on the left = 30° ( vertically opposite angle ), so
∠ 1 = 180° - 30° - 65° = 180° - 95° = 85°
It doesn't equals zero . it's not defined. or infinity
Answer:
in the numerator
in the denominator
Step-by-step explanation:
First fraction simplifies to:
Dividing my a fraction is the same as multiplying by the reciprocal, so the second fraction simplifies to:
So the equation becomes:
The (x+3) and (x+5) terms cancel out, so what your left with is
Expanding this term you get the answer:
in the numerator
in the denominator
