options are provided below...i hope this helps! :)
Step-by-step explanation:
well if the angles are vertical then ADC would be the same as ABC with 40 degrees
if the angles are corresponding, then they both are 40 degrees
if they are complementary angles, then they add up to 90 degrees
so the angle ADC would be 50 degrees
if they are supplementary angles, then they add up to 180 degrees. so ADC would be 140 degrees
X would equal 0 because u would use the distribution 3x+3=3x+3 and then subtract three from the three on the other side and then subtract 3x from 3x and then 0
The two short sides must be longer than those required in an isosceles right triangle. The ratio of side length to hypotenuse length in a 45°-45°-90° triangle is 1 : √2. So, such a triangle requires side lengths of 30/√2 ≈ 21.213 inches. Its perimeter will be about
... (30 +21.213 +21.213) in = 72.426 in
Since the perimeter needs to be slightly longer than that for the triangle to be acute, the smallest possible perimeter is ...
... 72.43 in
Answer:
The answer is −1.125...

2(9x + 3) + 5x = 48 + 2x
18x + 6 + 5x = 48 + 2x
23x + 6 = 48 + 2x
23x - 2x = 48 - 6
21x = 42
x = 42/21
x = 2
