Answer:
7, 13 3,7 17,3 13,2
Step-by-step explanation:
8 so D since -5 becomes a posit and then add 3
Answer:0.175 m/s
Step-by-step explanation:
Given
Two sides of length 9 and 13 m
angle between them is increasing at an angle of 0.02 rad/min
rate of increasing of third at 
let a=9
b=13
c=unknown side
Now using cos rule of triangle


Differentiating both sides we get

at 
c=11.53 m
substituting values we get


Answer:
Step-by-step explanation:
in an isocelles trapezoid, we have the properties:
the lower base angles are congruent
the upper base angles are congruent
we have an angle= 44
the angle #3= 44 because of the properties
so the lower base angles are equal and equal to 44
sum of the angles in trapezoid=360
360-(44*2)=360-88=272
upper base angles are equal
272/2=136
angle1=angle2=136
