Given that A, O & B lie on a straight line segment, evaluate obtuse ∠AOC.

Evgesh-ka [11]

Answer:

AOC = 124°

Step-by-step explanation:

Angle on a straight line is 180°, therefore, the sum of the three angles shown is 180;

This can be written like so:

(3x + 94) + (x + 30) + (2x - 4) = 180

This equation can be solved to find x:

6x + 120 = 180

6x = 180 - 120

6x = 60

x = 10

AOC = 3(10) + 94

= 30 + 94

= 124

What is the greatest common divisor of 33489, 3948, and 3949

storchak [24]

33489 = 32×612

3948 = 22×3×7×47

3949 = 11×359

GCD = 1

33489 / 1 = 33489

3948 / 1 = 3948

3949 / 1 = 3949

Rewrite the exponential expression 25^3/2as a radical expression-<br> plss helpp

Agata [3.3K]

Answer:

$\huge\boxed{\sqrt{25^{3}}}$

Step-by-step explanation:

When we have a number to a fraction power, we need to note that

It's the same as taking the denominator root of the base to the numerator power

Basically, for example, $5^{\frac{1}{2}}$ is the same as $\sqrt{5}$ since the numerator is 1 ( $5^1 = 5$ ) and the denominator is 2 ( $\sqrt{5}$ ).

Applying this same logic to $25^{\frac{3}{2}}$ -

$25^{3}$

$\sqrt{25^3}$

Hope this helped!
