What you're looking for is c so you can add a, b, and c together to get the material. To do this you need to use this formula, otherwise known as Law of Cosines:
c^2 = a^2 + b^2 - 2abcosC
c^2 = 25600 + 25600 - (2)(160)(160)(cos85)
c^2 = 51200 - (51200)(cos85)
c^2 = 51200 - (<span>-50400.084)
c^2 = </span><span>101600.084
c = 318.749
c + a + b = 638.749 or 639 ft if you're looking for a whole number
Keep in mind this answer is if what you're looking for is the perimeter, please let me know if it's the area you are looking for</span>
Answer:
24 picked 2 or more
Step-by-step explanation:
At least 2 means 2 or more
Add up all the x's
2: 7
3: 9
4: 8
total: 24
Answer:
4th Option
Step-by-step explanation:
When we look for side <em>x</em>, we have multiple ways:
cos60° = 10/x
x = 10/cos60°
sin30° = 10/x
x = 10/sin30°
sin60° = 15/x
x = 15/sin60°
cos30° = 15/x
x = 15/cos30°
Out of these choices, only the 4th Option is present, so that is our answer.
The sides of the isosceles triangle are two equal legs and the remaining side is called base.
Answer:
A. must be proportional because the points lie in a straight line
