Answer:
6. 60°
7. 5.19559
8. 7.96011
Step-by-step explanation:
6. The sum of angles in a triangle is 180°, so the remaining angle is ...
180° -40° -80° = 60°
7. The lengths of sides are proportional to the sine of the opposite angle (Law of Sines).
a = c·sin(A)/sin(C) = 7·sin(40°)/sin(60°) ≈ 5.19559
8. Same explanation as 7.
b = c·sin(B)/sin(C) = 7·sin(80°)/sin(60°) ≈ 7.96011
Answer:
I think it might be A: 75< x<84
Step-by-step explanation:
but i am not sure
Answer:
B) No, they are not congruent.
Step-by-step explanation:
The answer is A: 5
Any answer with 0 doesn't work because then the denominator would be 0 as well, and negative 5 does not make the numerator equal to 0.
