What is the value of x? show work 10 points

Mathematics
1 answer:
Vinvika [58]3 years ago
7 0

Answer:

x = 38

Step-by-step explanation:

The two angles in the picture are supplementary (sum of angles add up to 180°). That fact gives us the equation:

140 + (x + 12) = 180.

Subtracting 140 + 12 from both sides gives:

x = 38

A triangle has side lengths of 7 in., 9 in., and 11 in. Determine whether this is a right triangle and why.
Harlamova29_29 [7]

Answer:

Not a right triangle.  See below for my reasoning.


Step-by-step explanation:

If this is a right triangle, then the sum of the squares of the two shorter sides will equal the square of the longest side:  7^2 + 9^2 = 11^2 => 49 + 81 = 121   But this is false.
