C, but get someone else opinion too
4/9+1/5=20/45+9/45=29/45 of the wall is covered up by two couches
Part 1)
we know that
the property of cyclic quadrilaterals for which opposite angles are supplementary
then
m∠A°+43°=180°------------> m∠A=180°-43°=137°
the answer is m∠A=137°
Part 2) <span>Quadrilateral ABCD is inscribed in a circle. What is the measure of angle A?
we know that
</span>the property of cyclic quadrilaterals<span> for which opposite angles are supplementary
then:</span>
<span>m∠A+m∠C=<span>180<span>∘
(2x+9)+(3x+1)=180---------------> 5x+10=180
x=(180-10)/5=34
</span></span></span>m∠A=2x+9-------------> 2*34+9=77°
<span>
the answer is </span>m∠A=77°<span>
</span>
So the ratio is 40/26 = 1.54
24 ÷ 1.54 = 15.58
2x-4 = 15.58
2x = 19.58
x = 9.8
Answer:
6 seconds
======================================================
Step-by-step explanation:
let the entire length of path x
The object travels (1/8) of the length of the path (3/4) in second.
using the ratio and proportion to find the total time does it take the object to travel the entire length of the path as following
Length : time
1/8 x : 3/4 sec.
x : (total time)
using scissors metod
Total time = x * (3/4) / ( 1/8 x) = (3/4) / (1/8) = 6 seconds
