Answer:
20300m^2
Step-by-step explanation:
first try to imagine the shape bisected into a rectangle and a triangle
to find the missing part of the triangle or the bottom side you need to subtract 70m from 140 m
140m-70m=70m this will be the base of your triangle
now you need the side
230m-60m=170
triangle formula base x height/ 2
70m x 170m=a
11900m=a
now the rectangle
base x height=a
60m x140m=a
8400m=a
finally add the two quantities together
8400m+11900m=a
20300m^2=a
Answer:
b = sqrt(39)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2
5^2 + b^2 = 8^2
25+b^2 =64
b^2 =64-25
b^2 =39
Take the square root of each side
b = sqrt(39)
Answer:
answer is <u>6.8 m</u>
Step-by-step explanation:
√46.24 m
= 6.8 m
Angle 10 is 140 degrees
Angle 2 = Angle 10 = 140 degrees (Vertically Opposite Angles)
Angle 5 + Angle 4 = Angle 2 (Corresponding Angles)
Angle 5 + Angle 4 = 140
90 + Angle 4 = 140 (Angle 5 is 90 degrees because c is perpendicular to d)
Angle 4 = 50
I'm thinking C because if it bisects it, it divides it which means it's it midpoint.
