Answer: Um, The answer is 1, 12, –3.
Step-by-step explanation:
Answer:
<h2>b = 16.7</h2>
Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side b
Using Pythagoras theorem we have
a² = b² + c²
where
a is the hypotenuse
Substituting the values into the above formula we have
<h3>

</h3>
We have the final answer as
<h3>b = 16.7 to one decimal place</h3>
Hope this helps you
so you do 5 1/4 minus 3/4 and then you get your awnser
It is NOT a right triangle because a^2+b^2 does not equal c^2.

Answer:
For the parallelogram to be a rectangle, at least one angle must be a right angle or a 90° angle, we know that:
13x + 34° + 10x + 10° = 90°
=> 13x + 10x = 90° - 34° - 10°
=> 23x = 46°
=> x = 46°/23 = 2°
