In order to prove that the triangles are congruent by SAS (Side Angle Side) you would have to assume that side AB and AD are equal (isosceles triangle) so that the base angles, angle ABC and angle ADC are congruent. So once you know that two sides and the angle in between them are indeed congruent you can reason for SAS.

12x cubed - 4x squared

pashok25 [27]

Answer:

$4x^2\left(3x-1\right)$

Key:

• $a^{b+c}=a^ba^c$

• Factor out the last leading term standing to solve in the end.

Step-by-step explanation:

$12x^3-4x^2\\x^3=xx^2\\=12xx^2-4x^2\\=4\cdot \:3xx^2-4\cdot \:1\cdot \:x^2\\=4x^2\left(3x-1\right)$

The angle from a stake in the ground to the top of a tree is 60 degrees. If the height of the tree is 40 feet, what is the dista

Nonamiya [84]

Answer:

23.09 ft

Step-by-step explanation:

Here we are given that the angle from stake in ground to the top of the tree is 60° and the height of the tree is 40ft . We are interested in finding out the distance from stake to the bottom of the tree . For figure refer to the attachment .

From the figure , BC = 40ft which is the perpendicular of the right angled triangle ABC . Also assume that AB = x ft , which is the base of the triangle .
