1. 4 inside angles must sum to 360:
X = 360-45-65-95 = 155
2. All the outside angles must sum
To 360:
2x + 70+ 86 + 9 = 2x + 248
2x = 360-248
2x = 112
X = 112/2 = 56
3. Sum of interior angles for 6 sides figure = 720.
X = 720 - 90-120-130-140-150
X = 90
4. Exterior angles sum to 360
4x +x + 98 + 162 = 360
5x + 260 = 360
5x = 100
X = 100/5
X = 20
X is one angle
X+78 is the second angle
Add them together
2x+78=90
Subtract 78 from both sides
2x=12
X=6
One angle is 6 the other angle is 84
Answer:
it is up
Step-by-step explanation:
Answer:
The length of the ramp is 7.3 meters.
Step-by-step explanation:
The length of a triangle's side must be less than the sum of its two other sides. It also cannot have the same value as its other combined sides.
7 + 2 > 7.3
2 + 7.3 > 7
7 + 7.3 > 2
<em>r</em> is also longer than 7 meters, so that leaves option b. as your answer.
