Answer:

<em> (1). x = 14 ; (2). 70°</em>

Step-by-step explanation:

<em>(1).</em> m∠ACD = m∠A + m∠B

6x + 2 = (2x + 1) + (3x + 15)

6x - 5x = 14

<em>x = 14</em>

<em>(2).</em> m∠ABC = 180° - m∠CBD = 140°

<em>m∠A</em> = m∠C = 140° ÷ 2 = <em>70°</em>

PLEASE help me !!!! i dont know the exponent
Serggg [28]

Answer:

24\sqrt[3]{x^{7}}

Step-by-step explanation:

The exponent rule that applies to products like this is ...

... (a^b)(a^c) = a^(b+c)

In your problem, this is

... x^(1/3)·x^2 = x^(1/3 +2) = x^(1/3 +6/3) = x^(7/3)

This fractional exponent translates to the root of a power:

... = (x^7)^(1/3)

In typeset form, it is ...

\sqrt[3]{x^{7}}

You have already figured correctly that the coefficient is 3·8 = 24.
