Answer: C= 24
B= 4
Step-by-step explanation:
The ratio between the two triangles is 1:2
C = 12 × 2 = 24
B = 8 ÷ 2 = 4
Answer:
x ≈ 34.9
Step-by-step explanation:
Using the sine ratio in the right triangle
sin35° = 
= 
Multiply both sides by x
x × sin35° = 20 ( divide both sides by sin35° )
x= 
≈ 34.9 ( to the nearest tenth )
Answer:
3.04
Step-by-step explanation:
three and four-hundredths =
= 3 and 4/100
= 3 + 4/100
= 3 + 0.04
= 3.04
Now cos⁻¹(0.7) is about 45.6°, that's on the first quadrant.
keep in mind that the inverse cosine function has a range of [0, 180°], so any angles it will spit out, will be on either the I quadrant where cosine is positive or the II quadrant, where cosine is negative.
however, 45.6° has a twin, she's at the IV quadrant, where cosine is also positive, and that'd be 360° - 45.6°, or 314.4°.
now, those are the first two, but we have been only working on the [0, 360°] range.... but we can simply go around the circle many times over up to 720° or 72000000000° if we so wish, so let's go just one more time around the circle to find the other fellows.
360° + 45.6° is a full circle and 45.6° more, that will give us the other angle, also in the first quadrant, but after a full cycle, at 405.6°.
then to find her twin on the IV quadrant, we simply keep on going, and that'd be at 360° + 360° - 45.6°, 674.4°.
and you can keep on going around the circle, but only four are needed this time only.
