Answer:
1) ΔACD is a right triangle at C
=> sin 32° = AC/15
⇔ AC = sin 32°.15 ≈ 7.9 (cm)
2) ΔABC is a right triangle at C, using Pythagoras theorem, we have:
AB² = AC² + BC²
⇔ AB² = 7.9² + 9.7² = 156.5
⇒ AB = 12.5 (cm)
3) ΔABC is a right triangle at C
=> sin ∠BAC = BC/AB
⇔ sin ∠BAC = 9.7/12.5 = 0.776
⇒ ∠BAC ≈ 50.9°
4) ΔACD is a right triangle at C
=> cos 32° = CD/15
⇔ CD = cos32°.15
⇒ CD ≈ 12.72 (cm)
Step-by-step explanation:
The answer is b,
if you put them all in decimal form it would look like this:
-6.53, -6.25, 6.57, 6.75
A, dilation because the shape got larger. The other three options just move it around
Answer:
4^6
Step-by-step explanation:
Answer:
25 slugs
Step-by-step explanation:
If this is a physics-based problem, which it appears to be, then the formula for finding mass is
w = mg, where w is the weight, m is the mass, and g is acceleration due to gravity. We have our weight and our gravity, so
800 = m(32) so
m = 800/32 and
m = 25 slugs
This answer does not include significant digits. If it needed to, then your answer would be 30 slugs.
