So it takes half an hour to set up a computer work station. half an hour = 30 minutes. so we know 2 half hours = 1 hour. so 7-2=5 so 1 hour 5-2=3 s0 that makes 2 hours. 3-2=1 so that would be 3 and a half hours or 3.5
By sine rule,
sin40/45= sin<B/60
Angle B= 59.0
Remaining angles are 59.0 and 81.0
Y=-2 1/2 explosion is the key ingredient in this factor
Answer:
5
Step-by-step explanation:
25x+5=130 ( corresponding angles are congruent )
25x=125
x=5
