Answer:
A is
Step-by-step explanation:
Answer:
the triangle above is an isoceles triangle
therefore the base angles are equal
So we have:
X + X + 38= 180
2x = 180-38
2x = 142
X = 71°
Answer:
B 0 ≤x≤9
Step-by-step explanation:
The domain is the input values of the graph. In this graph it is the values that the time variable takes.
Time can take 0 seconds to 9 seconds
0 ≤x≤9
Width = x
length = 3x + 4
x + x + 3x + 4 + 3x + 4 = 60
add
8x + 8 = 60
subtract
8x = 52
x = 6.5
width = 6.5
length = 23.5
