Answer:
172.27 in
Step-by-step explanation:
Apply the Sine Rule
Sine Rule is given as:
c = x = ?
C = 180 - (52 + 48) = 80° (sum of triangle)
b = 130 in.
B = 48°
Plug in the values
Multiply both sides by sin(80)
172.274641 = x
x = 172.27 in. (to 2 decimal places)
Answer:
Step-by-step explanation:
- <em>Sum of exterior angles of any polygon is 360°</em>
<h3>Exercise 8</h3>
<u>Sum of given angles:</u>
- 2x + 60° + 64° + 36° + 48° = 360°
- 2x + 208° = 360°
- 2x = 360° - 208°
- 2x = 152°
- x = 76°
<h3>Exercise 9</h3>
<u>Sum of given angles:</u>
- x + 90° + 109°+ 73° = 360°
- x + 272° = 360°
- x = 360° - 272°
- x = 88°

Answer:
y = x + 7
y = (-x) + 2
X + 7 = (-x) + 2
X + X = 2 - 7
2x = (-5)
<h3>x = (-5)/2 </h3>
Putting the value of X in equation
Y = (-5/2) + 7
Y = (-5)/2 + 7/1
Equalising the denominator by Taking LCM
Y = (-5)/2 +14/2
Y = ( -5 +14)/2
<h3>Y = (9)/2 </h3>
So that would be the same thing as 5 4/5 - 3 2/7
Put them in mixed fractions to become 29/5 - 23/7
Multiply one side by 7 and one side by 5 to get the same denominator
203/35 - 115/35
Now subtract the numerators to get
88/35
Or if they want it inixed numbers then 2 18/35
