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.
Answer:
...
Step-by-step explanation:
1. B
angle A is 63 since 27+90= 117, 180-117= 63 (since a straight line is 180°)
2. 7x + 10 = 150 (since they are vertical angles)
7x = 140
x = 20
now plug in 7(20) +10
140+10=150
(6x7)x5 = 6x(7x5), hope this helps
24. 9×4=36 4×-3=12 so 36+(-12)=24
