Answer:
105
Step-by-step explanation:
The interior angle for R is supplementary to the 155 degree angle
(they add to 180)
180-155=25
The sum of the interior angles of a triangle is always 180
180-50-25= 105
<span>The word in question is "starting." Taking away the second "t" gives "staring." Next, taking away the "a" gives "string," and taking away the "r" gives "sting." Further, dropping the second "t" gives "sing." Next, removing the "g" leads to "sin," the "s" gives "in," and finally taking away the "n" leaves the word "I."</span>
