3. Find m D (2x+14) (x + 7) E B 60 23 53 30

pickupchik [31]

Answer:

Step-by-step explanation:

∠ABC + ∠CBD = 90 so filling in the expressions for these angles:

(2x + 14) + (x + 7) = 90 and

3x + 21 = 90 and

3x = 69 so

x = 23. To find the measure of angle ABC in particular, we sub in a 23 for x:

x + 7 --> 23 + 7 = 30°, the last choice there.

HELP PLEASE !!!!!!!!!!!!!!!

valina [46]

(f×g)(x) = (fg)(x)

(f×g)=(3x²+5)× (x-2)

use the foil method:

(fg)(x)=3x³-6x²+5x-10

so it is C which is correct

The cube root of a number is 2. Write an equation, using x, that represents this situation.

Kay [80]

Answer:

x - 8 = 0

Step-by-step explanation:

Since, the cube root of a number is 2.

Let the number be x.

Therefore,

$\sqrt[3]{x} = 2 \\ cubing \: both \: sides \\ {( \sqrt[3]{x})}^{3} = {(2)}^{3} \\ x = 8 \\ x - 8 = 0$

find the missing angle measure in each triangle. Then classify the triangle as acute, right, or obtuse. PLEASE ANSWER QUICK ILL

larisa86 [58]

X=72 cause 180-(51+57) so 180-108 and the triangle is acute cause all of the angle measures are below 90 degrees.

So your answer is
x=72
Acute Triangle
