Answer:
10.6 ft
Step-by-step explanation:
to find the diagonal length of the stairway we can use the pythagorean theorem or a^2 + b^2 = c^2
6'4" is also 6 1/3' or 19/3'
8'6" is also 8 1/2' or 17/2'
now square them both
361/9 + 289/4
make them have the same denominator
1444/36 + 2601/36
add them
4045/36
take the square root
10.6000524 is your answer
10.6 ft
Answer:
Angles of a rhombus equal 360. Bisected adjacent angles are equal. Opposite angles are equal. Same side angles are supplementary
Step-by-step explanation:
One angle is 40, the adjacent bisected angle is also 40. Opposite angles are equal so the opposite angle is 80 degrees (the bisected angles are each 40).
Same side angles are supplementary (add up to 180 degrees) So the supplementary angle of the 80 degree angle is 100 degrees, and its opposite angle is also 100 degrees. The angles of a rhombus add up to 360...80+80=100+100= 360.
Well its using the angle bisector theorem, so i think that the anwser
2x10^-10
1x10^-10
8x10^-11
7x10^-11
Answer:
the perimeter is 152, the area is 910
Step-by-step explanation:
perimeter = 20+50+20+10+6+15+6+25
=152
area = (20×50)-(6×15)
= 1000-90
= 910
hope that helped!
