SAS similarity theorem: When two triangles have corresponding angles that are congruent and corresponding sides with identical ratios, the triangles are similar.
Two right angles are always congruent, but corresponding sides not always have identical ratios. For example, first right triangle has two legs of 3 and 4 lengths. Second triangle has two legs of 5 and 12 lengths. Then \frac{3}{5}  \neq  \frac{4}{12}. That is the mistake.

<span>Daniel has not satisfied all the conditions of the theorem. The corresponding sides of each of the right triangles must also be in proportion for the triangles to be similar.</span>

Does anyone know this ? i'm stuck.. i'll give you brainliest and 15 points !! show work.

Answer:

x = 7

Step-by-step explanation:

The angle adjacent to the 70 degree angle is also 70 degrees.  We assume that there are four 90-degree angles in the center of the figure.  Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).

Solving  8x - 36 + 70 + 90 = 180 for x:

              8x - 36 = 20, or 8x = 56.

Dividing both sides by 8 yields x = 7.

If -3x-8=16 what is the value of -2(x-7)
777dan777 [17]

Answer:

-3x-8=16

-3x = 16+8

-3x = 24

x = 24/-3

x = -8

= -2(x-7)

= -2(-8-7)

= 30

Hope this helps you. Do mark me as brainliest.
