Answer:
=136
Step-by-step explanation:
Lets solve the triangle using the sine formula.
c/sine C=a/sine A
C= 180-(72+16)
=92°
61/Sin 92=a/sin 72
a=(61 sin 72)/sin 92
=58.0
Solving for b:
c/sin C= b/Sin B
61/sin 92= b/Sin 16
b=(61 Sin 16)/Sin 92
=16.82
Perimeter = 61 +58+ 16.82 = 135.82
Answer =136 to the nearest whole number.
1/2x + 3 = 2/3x + 1....multiply everything by the common denominator of 6
3x + 18 = 4x + 6
3x - 4x = 6 - 18
-x = - 12
x = 12 <====
multiplying by the common denominator will get rid of the fractions
Answer:
Fig (c)
Step-by-step explanation:
30° + x° + x° + (180° - 70°) + (180° - 60°) = 540°
260° + 2x° = 540°
x = 280° /2
x = 140° (ANS)
