x=6
Answer:
20km
jus split it up into parts\
5+5+2.5=12.5
8+8+4=20
Answer:
x = 52
The exterior angle of a triangle is equal to the sum of the opposite interior angles
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
x+72 = 90+34
Combine like terms
x+72 = 124
Subtract 72 from each side using the subtraction property of equality
x+72-72 = 124 -72
x =52
Amplitutde:
Normally for sinx amplitude is 2 (1 +1). In the case when it is half sine amplitude is halved, therefore 0.5 +0.5 = 1 Paramers alpha = 2x does not matter because it only stretches the graph horizontally.
2.62 is the answer but there’s actually way more numbers than that
