Mathematics
1 answer:
slega [8]2 years ago

Answer: 66 degrees

Step-by-step explanation:

Sum of the angle measures is 180, so:

71 + x + 49 + x + 72 = 180

2x + 192 = 180

2x = -12

x = -6

Meaning the measure of angle A = -6 + 72 = 66 deg.

Can someone help me with this question? Whoever helps will get brainliest answer. thank you.

Answer:

Final answer is x^2.

Step-by-step explanation:

Given expression is x^{\left(\frac{4}{3}\right)}\cdot x^{\left(\frac{2}{3}\right)}

Now we need to find about what is product of both factors.

We see that both factors are in exponent form having equal base "x".

So we can apply formula: x^m\cdot x^n=x^{\left(m+n\right)}

x^{\left(\frac{4}{3}\right)}\cdot x^{\left(\frac{2}{3}\right)}

=x^{\left(\frac{4}{3}+\frac{2}{3}\right)}

=x^{\left(\frac{4+2}{3}\right)}

=x^{\left(\frac{6}{3}\right)}

=x^2

Hence final answer is x^2.

Answer:

YES IT IS

Step-by-step explanation:

2-3 + 3.3

= -1 + 3.3

= -4.3

We learn that:

Rational number: rational number is the number that can be written as a/b (a and b would be intergers and b is not equal to 0). Rational number would be most of numbers we use in out life, except Square root and Pi number.

In this case, -4.3 can be write as -43/10

So YES it would be a rational number

Hope this helped :3
