<h2>Answer: The perimeter of angle ABC = 61.911 Step-by-step explanation: Since we are given two angles and the length of one side, we apply the SINE RULE Sine Rule = sinA / a = sinB / b = sinC / c where A, B, C are the angles of the triangle
AND
a, b and c are the length of the sides of the triangle. BUT FIRST, lets get the value for the missing angle CAB Sum of angles of a triangle = 180°
angle CAB = 180° - (40° + 49° )
angle CAB = 180° - 89
CAB = 91° To get the PERIMETER of ΔABC, we must get the length of all the three sides of the triangle using THE SINE RULE sin49° / 19.5 = sin 40° / AB = sin91° / CB 0.755/19.5 = 0.643 / AB
Cross multiplying
AB * 0.755 = 0.643 * 19.5
AB = 12.539 / 0.755
AB = 16.608
LETS SOLVE FOR CB
sin49° / 19.5 = sin91° / CB
CB * sin49° = 19.5 * sin91°
CB * 0.755 = 19.5 * 0.999
CB = 19.481 / 0.755
CB = 25.803 Therefore, AC = 19.5
AB = 16.608
CB = 25.803 The perimeter of ΔABC equals to the sum of AC, AB, CB
= 19.5 + 16.608 + 25.803
= 61.911.</h2>
Answer:
3 +2 = 5 and 12 + 5 = 17
Step-by-step explanation:
i hope this helps im not sure if its frght or if it helps sorry if its wrong.
Answer:
The given equation is
⇒y≥
As domain of the function is 3 x-2≠0
x≠2/3
⇒For different values of x we get different values of y.
When, x>2/3 , we get positive values of y.
So , y≥ 0
and when x< 2/3 , we get values of y which are negative.
i.e y≤0
At x=2/3, function is not defined.So at that point there does not exist any value of y.
Answer: 255 Teenagers.
Solution: If 170 is 2/3 of the teenagers then 85 is 1/3. So, 170 + 85 = 255.
