-240+360=120
The answer is 120 degrees.
Answer:
1. -|12|
2. -5
3. -1
4. |-1|
5. 12
Step-by-step explanation:
Answer:
A. 8.66 feet
B. 12.59 feet
C. Area of triangle when is 129.9 square feet. Area of triangle when is 188.85 square feet. Increasing the angle increases the area.
Step-by-step explanation:
The equation that models the height of the triangle is:
Where,
- is the height, and
- is the angle
A.
When , the height is:
B. When
C. <em>To find the area of the isosceles triangular shaped garden, we use the </em><em>formula for the area of the triangle</em><em>:</em>
Where,
- A is the area
- b is the base, which is given as 30 feet, and
- h is the height [8.66 feet when the angle is 30 & 12.59 when angle is 40]
<u>When Vance uses , the area is</u>:
square feet
<u>When Vance uses , the area is</u>:
square feet
So we see that when the angle is more, the area is also more.
The distance from point Y to the y-axis is 4 units and the distance from point Z to the y-axis is 3 units, then the lelgth of the segment YZ is 4+3=7 units.
If <span>a scale factor is 3, then the length of Y'Z' will be 7·3=21 units.

P.S. In the added picture you can see trapezoid ABCD that was dilated by a scale factor 3 about the origin. This may help to understand that all linear values after dilation become multiplied by scale factor.
