Answer:
127.1 m
Step-by-step explanation:
We are given the value of the adjacent side and we are to find the value of the opposite side
Tan would be used to determine this value
Tan 23 = opposite / adjacent
1.5882 = x / 80
x = 80 x 1.5882
x = 127.056 m
x = 127.1m
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
Please find attached a diagram showing the angle of elevation
The answer is 3_4/11. The "_" indicates it's not the same number. So you don't get confused.
When repeating, you put a 99. Not 100. So, this will be 36/99. Now, you simplify. Also add the 3. You then get 3_4/11.
Proof:
x=0.6...
10x=6.6...
-x=0.6...
9x=6
x=2/3
2/3=0.6...
Answer:
108 are singing along
Step-by-step explanation:
Since theres 5 not singing a long for every 3 just divide 180 by 5 which gets you to 36 then times that by 3
Answer:
27°
Step-by-step explanation:
Let line AB be extended to touch line DC at point F, thereby forming triangle BCF.
∠ABC + ∠BCE = 180° (sum of interior angles in a transversal).
∠ABC + 48 = 180
∠ABC = 180 - 48 = 132°
Also in triangle ADF, ∠ADF + ∠DFA + ∠FAD = 180 (sum of angle in a straight line)
85 + ∠DFA + 25 = 180
∠DFA + 110 = 180
∠DFA = 180 - 110 = 70
∠DFA = 70
∠DFA + ∠BFC = 180° (sum of angle on a straight line)
∠BFC + 70 = 180
∠BFC = 180-70 = 110
∠BFC = 110°
∠ABC + ∠CBF = 180° (sum of angle on a straight line)
132 + ∠CBF = 180
∠CBF = 1800 - 132 = 42
∠CBF = 42°
In triangle BCF:
∠BFC + ∠CBF + x = 180° (sum of angle in a triangle)
42 + 110 + x = 180
x + 152 = 180
x = 180 - 152
x = 27°
