Answer:
t° = 11° s°= 71°
Step-by-step explanation:
79° + t° =90° (Given)
t°= 90° - 79°
t°= 11°
s°+79°+11°+19° =180° (angles on an str line)
s° = 180° - 109°
s° = 71°
Answer:
its not very clear can you take a picture again?
Step-by-step explanation:
The remaining side using cosine theorem is:
BC ^ 2 = 36 ^ 2 + 36 ^ 2 - 2 * 36 * 36 * cos (65)
BC = root (1496.573466)
BC = 38.68557181
Then, for the area we have:
A = root (s (s-a) * (s-b) * (s-c))
s = (a + b + c) / 2
Substituting:
s = (36 + 36 + 38.68557181) / 2
s = 55.34278591
A = root (55.34278591 * (55.34278591-36) * (55.34278591-36) * (55.34278591-38.68557181))
A = 587.2874463
Rounding off we have:
A = 587.3
Answer:
A = 587.3
