Answer:
A = 9.9648
Step-by-step explanation:
if the triangle is equilateral =>
P = 3L => L = 14.4/3 = 4.8
A = L²√3/4
= (4.8)²√3/4
= 23.04√3/4
= 5.76×1.73
= 9.9648
Answer:
C.94
Step-by-step explanation:
The alternate interior angle of angle c is angle 6. So from there you just subtract the 84 from the 180 to get the 94 degrees.
25
The triangle given by 9, unknown, and 15 and the triangle given by 15, unknown, and x are similar triangles and therefore 9:15 = 15:x
X is 25 in this case
