Answer:
Step-by-step explanation:
5:4:3 = x:y:2
4:3 = y:2 Cross multiply
3y = 8 Divide by 3
y = 8/3 = 2.66'
5/x = 3/2
3x = 10 Divide by 3
x = 10/3
x = 3.33
Length of the wood = 2.66 + 3.33 + 2
Length of the wood = 8 feet
2/10 x 2/10 = 4/10 that can be a expression sorry if im wrong
Answer:
Step-by-step explanation:
- <em>Refer to attached. Point J, segment BJ and angle measures added.</em>
<u>Step 1, find BJ</u>
- BJ / AB = sin 20° ⇒ BJ = AB sin 20° ⇒ BJ = 600 sin 20° ≈ 205.2 ft
<u>Step 2, find BP</u>
- BJ/BP = cos 75° ⇒ BP = BJ / cos 75° ⇒ BP = 205.2/cos 75° ≈ 792.8 ft
<u>Step 3, find PQ</u>
- PQ/BP = sin 35° ⇒ PQ = BP sin 35° ⇒ PQ = 792.8 sin 35° ≈ 454.7 ft
<u>Step 4, find the elevation of peak P</u>
- Height above sea level = 6500 + 454.7 ≈ 6955 ft (rounded)
Answer: 40
Step-by-step explanation:
Since this is a scalene, we know there are two 70 degree angles. Because triangles are 180 degrees, and 70 + 70 = 140, 180 - 140 = 40.
Hope this helps,
