There's the obvious symmetry ultimately because the radii OA and OB are hypotenuses of congruent right triangles. We can just eyeball the figure and see AB=BC, at least approximately, so the full chord AC=9+9=18
Answer: A. 18 units
Answer:
it should be B
mark me as the brainliest please
Step-by-step explanation:
width of rectangle(w)=x let
length (l)=4x
perimeter of rectangle=70
2(l+w)=70
2(4x+x)=70
8x+2x=70
10x=70
x=70/10
x=7
again,
- length =4x=4×7=28cm
- width=x=7
area of rectangle =l×w
hope it helps.
Answer:
50 deg
Step-by-step explanation:
In an right triangle, the acute angles are complementary. That means their measures have a sum of 90 deg.
m<C + m<B = 90
7x - 20 + 4x = 90
11x = 110
x = 10
m<ACB= 7x - 20
m<ACB = 7(10) - 20
m<ACB = 70 - 20
m<ACB = 50
Answer: m<ACB = 50 deg
