Answer:
y = 41°
Step-by-step explanation:
∡ y and 139° are adjacent angles and sum to 180° , that is
∠ 1 + 139° = 180° ( subtract 139° from both sides )
∠ 1 = 41°
Answer:
96 + 150 + 2x + x = 360⁰
240 + 3x = 360⁰
3x = 120
x = 40⁰ hope it's help you
Answer:
2.5
Step-by-step explanation:
A triangle ABC with vertices A(0, 0), B(0, 4), and C(6, 0) is dilated to form a triangle A'B'C' with vertices A′(0, 0), B′(0, 10), and C′(15, 0). If the center of dilation is point A or A' (the origin), then

Since
- AB=4;
- A'B'=10;
- AC=6;
- A'C'=15,
then the scale factor of the dilation is

Step-by-step explanation:
i juuts took this test
y=4x+40
x represents the number of minutes
y is the total
40 because he already graded 40 papers, and 4x because that's how many phred grades times the number of minutes
