Answer:
a) cannot be determined
b) a triangle can be drawn, but its dimensions cannot be determined
Step-by-step explanation:
<h3>a)</h3>
The vertical axis is labeled in units of kilometers. The horizontal axis is labeled as distance, with no units given. The line shown appears to descend from 12 units above ground level over a distance of 34 units along ground level. One could argue the slope is 12/34 = 6/17, but there is no indication the horizontal units are the same as the vertical units.
The slope of the graph cannot be determined, because we don't know the horizontal units.

<h3>b)</h3>
You can draw the triangle, but you cannot determine its dimensions.
Answer:
8: 90 degrees, 9: 165 degrees, 6: 81 degrees, 7: angles in the same segment are equal
Step-by-step explanation:
For question 8:
Notice how the line AB just barely touches the edge of the circle. We call this kind of line a tangent. The point O is at the center of the circle so the line OB is a radius. The angle between a tangent and a radius is always 90 degrees, so ABO is 90 degrees.
For question 9:
By the exact same logic as 8, ACO is also 90 degrees. The sum of interior angles in a 4 sided shape (a quadrilateral) is always 360 degrees. This means that 15 + 90 + 90 + x = 360 = 195 + x so x = 360 - 195 = 165
For question 6/7:
We use the theorem that the angles in the same segment are equal. This means that a is 81 degrees.

Answer:
x=9
Step-by-step explanation:
2(10-22×0)=(2x+2)
Applying BODMAS
2(10-0)=(2x+2)
2(10)=2x+2
2x+2=20
2x=20-2
2x=18
x=9
Vs<vu
cause smaller sides have smaller angels in front ofthem
