Step-by-step explanation:
- Given:ABCD is a rectangle, AC and BD intersect at O
- To prove: ∆ABC and ∆BAD are congruent.
- Proof:
The base angles of an isosceles triangle are the same.
Hence,
The degree of each base angle of each face is [(180-76)/2]= 52.
Answer:
5
Step-by-step explanation:
it can be found in two ways
f(n)-f(n-1) is common difference of the sequence.
knowing f(n) = f(n-1) + 5
f(n)-f(n-1)=5
so 5 is difference of the sequence.
other method is
f(1)=4
f(2)=?
f(n)=f(n-1)+5 n=2
f(2)=f(2-1)+5
f(2)=f(1)+5
f(2)=4+5=9
f(2)-f(1)=9-4=5
so 5 is difference of the sequence.
Answer:
73/20
Step-by-step explanation:
3=60/20
(60+13)/20
73/20
The mixture that is an equivalent ratio is:
1.5 white 2 blue is the answer to the question
Here are two paint mixtures: • 3 cups of white and 4 cups of blue. • 6 cups of white and 8 cups of blue. Both mixtures make the same color because they are in equivalent ratios. Which of these mixtures is also in an equivalent ratio? 5 cups white 6 blue 1 white 1 1/2 blue 4 white 3 blue 1.5 white 2 blue.
