I need help on solving these types of geometry problems! Teacher said the answer is 7 but I have to show work. Thank you!

The vertex where the two triangles touch forms a pair of vertical angles, so that the angles on opposites sides of the vertex are congruent. You're shown that two legs of both triangles are congruent. All this tells you that the two triangles are isosceles, and furthermore that they are similar because of the congruence of their "base" angles.

This means

$82^\circ=m\angle 2$

$\implies82=10x+12$

$\implies10x=70$

$\implies\boxed{x=7}$

What is the base of a triangle with a height of 14 cm and an area of 42 square cm?

sasho [114]

Answer:

$6cm$

Step-by-step explanation:

$area = \frac{1}{2} \times base \times height \\ 42 = \frac{1}{2} \times b \times 14 \\ 42 = \frac{14b}{2} \\ 42 = 7b \\ \frac{42}{7} = \frac{7b}{7} \\ base = 6cm$

hope this helps
