The entire figure could be taken as a trapezium
A=1/2h(a+b)
h=8, a=6 and b=10
A=1/2×8(6+10)
A=4×16
A=64sq Inch
Answer:
unit vector = -0.891i + 0.454j
Step-by-step explanation:
Given that;
magnitude of unit vector =
angle of 153° degrees from the x axis, with a positive y component
{ second quadrant }
so, x and y components of the vector are;
x component = 1 × cos(153°) = - 0.891
y component = 1 × sin(153°) = 0.454
⇒ -0.891i + 0.454j
Therefore, unit vector = -0.891i + 0.454j
For both problems, we can use the section formula.
1) 
2) 
Answer:
1. 16.62d + 26 = m 2. $152.34
Step-by-step explanation:
For the first part of the question you put the unknown variable multiplied by 16.62. Then add 26 which equals an unknown variable. For the second part, I multiplied 16.62 by 7 and added 26.
