A triangle will have a total of 180 degrees.

Since it is a right triangle, we know that one angle is 90 degrees. We also know that one of the other angles is 51.

90 + 51 + x = 180
141 + x = 180

Subtract 141 on both sides.

x = 180 - 41
x = 39

The value of b is 39 degrees.

What is 2*2^3 in expanded form?
katrin2010 [14]

Answer:

16

Step-by-step explanation:

To solve this question,we will have to understand some symbols in mathematics...

For example,* means ×

/ Means÷

We have so many of them

So back to the question

2*2^3 means 2 multiply by 2 raise to the power of 3

So 2^3 is 8

Therefore,2*8 means 2×8

It equals to 16

Therefore the final answer is 16

I hope you understand it better now
