Answer:
9.24 m to 2 DP's.
Step-by-step explanation:
Consider the right triangle formed from a side , altitude and 1/2 the base.
By pythagoras:
x^2 = 8^2 + (0.5x)^2 where x is the length of each side.
x^2 - 0.25x^2 = 64
0.75x^2 = 64
x^2 = 64/0.75 = 85.3333.
x = 9.2376 m.
Answer:
9.4 = x
Step-by-step explanation:
You are given the hypotenuse and the adjacent side, leading you to use cosine.
<u><em>Set it up:</em></u>
<u><em /></u>
<em><u>Multiply everything by 14, to remove it from the denominator:</u></em>
<em><u /></em>
<em><u>Multiply accordingly:</u></em>
9.36 = x
<em><u>Round to nearest tenth:</u></em>
9.4 = x
Answer:
x<-1 or x>11
Step-by-step explanation:
Set the equation x-5>6 and solve. You would then get x>11
For the second part, you want to flip the > sign into < and turn the 6 into -6. Solve the equation to get x-5<-6 which is then x<-1
