What is the missing angle
2 answers:
The missing angle is 53 degrees (82+45=127) (180-127=53)
The sum of interior angles in a triangle is 180°
So the expression would be
∠1 + ∠2 + ∠3 = 180°
Input the numbers to find the third angle
∠1 + ∠2 + ∠3 = 180°
82° + 45° + ∠3 = 180°
127° + ∠3 = 180°
∠3 = 180° - 127°
∠3 = 53°
The missing angle is 53°

Answer:
246 in^2
Step-by-step explanation:
Given data
Length= 8 in
Width= 3 in
Height= 9 in
SA= 2( lw + wh + hl)
substitute
SA= 2(8*3+ 3*9+ 9*8)
SA= 2(24+ 27+72)
SA= 2(123)
SA= 246 in^2
Hence the SA is 246 in^2
