Answer:
x=35²
Step-by-step explanation:
1. Since all pentagons have a total interior angle sum of 540, add all the terms together and set them equal to 540:
2. combine like terms. <u>(91, 92, -8, -5 and 125) (3x and 4x)</u>
3. subtract 295 from 540:
4. Divide 245 by 7.
Final answer:
<u>x = 35</u>

Step-by-step explanation:
As you know, dividing by a fraction is the same as multiplying by that fraction's inverse (or reciprocal). Any whole number is equivalent to the fraction that is that whole number divided by 1. (For example, 4 = 4/1.)
Answer:
see below
Step-by-step explanation:
The angle where chords cross is the average of the intercepted arcs. Here, that is ...
(37° +46°)/2 = (83°)/2 = 41.5°
Angle SUT is 41.5°.
_____
<em>Comment on the error</em>
The measure of an arc cannot be arbitrarily said to be the same as the angle where the chords cross. It will be the same if (a) the chords cross at the circle center, or (b) the opposite intercepted arc has the same measure. Neither of these conditions hold here.
