One angle is 40 degrees and the other is 50 degrees.

A complementary angle is 90 degrees.

As the ratio is 4:5 we can use the equation: 4x+5x=90

Solving it we get:
9x=90
x=10.

So the ratio is 4(10):5(10)

Meaning the two angles are 40 degrees and 50 degrees.

I hope this helps!

In the Fibonacci Sequence, each term after the first two terms is the sum of the preceding two terms. If the first two terms are
Snezhnost [94]

If the first two terms are 1 and 1, then what is the tenth term?

Answer:

The 10th term will be 55

Explanation:

In the Fibonacci Sequence, we add the previous digits to get the next digit. So, here 1st term is 1.

First term= 1

Second term = 0+1= 1

Third term= 1+1=2

Fourth term= 1+2= 3

Fifth term= 2+3= 5

Sixth term= 3+5= 8

Seventh term= 5+8 = 13

Eighth term= 8+13= 21

Ninth term= 13+21= 34

Tenth term= 21+34 = 55

So, the 10th term is 55.
