Apply the distributive property:<br> -3(x+2) =
vfiekz [6]

Hello skm413002!

\huge \boxed{\mathfrak{Question} \downarrow}

Apply the distributive property:

-3(x+2) =

\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}

By applying the distributive property, we can solve it as....

\sf \: - 3(x + 2) \\  =   \sf \: (- 3 \times x) -( 3 \times 2) \\  =  \large  \boxed{\boxed{ \bf - 3x - 6}}

<h3><u>Method</u><u> </u><u>:</u><u>-</u></h3>
  • Distributive property.

<h3><u>Steps </u><u>:</u><u>-</u></h3>
  • Multiply -3 with x & 2.
  • Add the 2 products.
  • You'll get the answer as <u>-3x </u><u>-</u><u> </u><u>6</u><u>.</u>

A triangle ABC is inscribed in a circle, such that AB is a diameter. What are the measures of angles of this triangle if measure
Katen [24]

Answer:

∠C=90°

∠A=67°

∠B=23°

Step-by-step explanation:

For angle C:

  Thales' Theorem states that an angle inscribed across a circle's diameter is always a right angle.

  Therefore, since AB is the diameter(hypotenuse) then angle C is the right angle. (90°)

For Angle A:

  The measure of arc BC= 134 degrees. We can just use a formula for an inscribed triangle. ∠A = 1/2 (mBC)

  ∠A= (1/2)134

  ∠A= 77°

For angle B:

  All triangle angles all add up to 180. We can just subtract angles A and C from 180°:

  ∠B = 180-(90+67)

  ∠B = 23°
