Answer:
AB = 5.2
AC = 5.2
m∠3 = 30 degrees
, m∠4 = 30 degrees
Step-by-step explanation:
Triangle ABO and ACO are both 30 60 90 triangles and are equal
Therefore If we have two sides then we can figure out the last side

Answer:
√205 +√178 +1 ≈ 28.6595
Step-by-step explanation:
The distance formula tells you the distance between points (x1, y1) and (x2, y2) is ...
d = √((x2 -x1)^2 +(y2-y1)^2)
Taken pairwise, the distances between the given points are ...
d1 = √((-10-4)^2 +(-4-(-7))^2) = √(196+9) = √205
d2 = √((3-(-10))^2 +(-7-(-4))^2) = √(169+9) = √178
d3 = √((4-3)^2 +(-7-(-7))^2) = √1 = 1
Then the sum of the distances gives the perimeter:
P = d1 +d2 +d3 = √205 +√178 +1 ≈ 28.6595
_____
In the attached figure, the distance "a" is the sum of the two long sides of the triangle.
Answer:
50% of 6/5 = 3/5
Step-by-step explanation:
Remember that 50%=1/2
Therefore, 50% of 6/5 = 1/2*6/5=6/10=3/5
Answer:
Step-by-step explanation: The area of the bedroom is
A=7yd^2
The total cost is the sum of the price rates times this area.
C=A•($21+$5)/yd^2
where C is total cost.
C=7yd^2•($21+$5)/yd^2
C=$182
