Answer:
r = 30°
Step-by-step explanation:
According to the Exterior Angle Sum Theorem, the exterior angle, which is 90°, is equal to the 2 interior angles, which are 60° and <em>r°</em>. We know that the angle next to the exterior angle is 90°, and since all angle sums add up to 180°, <em>r</em> = 30°.
Answer:
n=7/2
Step-by-step explanation:
distribute the 6
6n+18-4
then simplify the terms
6n+14= 7/2
and that is your final answer
100 * 1000 : 60 : 60 = 27.77 m/s
2 * (48 + 52) = 200
The perimeter of the parallelogram is 200!
Answer:
7 years
Step-by-step explanation:
27370 - 26986.82 = 383.18ft
0.2% = 0.2/100 = 0.002
27370*0.002 = 54.74
each year the montain reduce your elevation
54.74ft
then:
383.18/54.74 = 7
Answer:
7 years
