The angles should measure 180º.
<span>5° + 75°+ 100° = 180°
</span><span>10°+ 80°+ 90° = 180°
</span>
20° + 60° + 100° = 180°
45° + 45° + 45° = 135°
50° + 50° + 80° = 180°
So D does not represent interior angle measures of a triangle.
Hope this Helps!!
Option (A) 18 = 0.1s
Step-by-step explanation:
Every seventh-grade student at Martin Middle School takes one world language class.
Now we will form the equation as per statement of the question.
Let total students of seventh-grade = s
" one tenth of seventh grade students take French."
" Students who took French were 18."
So of s = 18
(0.1)s = 18
therefore, Option (A) 18 = 0.1s is the answer.
Is it ok if i say the answer oh well i will u can do it two ways but my way is 7-7=r then r+7=7r then 7r+4r=11r then 11r +r=12r then do nothing with the left over 7 and your answer is 12r×7 that is how you simplify it
