<h2>sum of angle of triangle is 180°</h2>
<h2>A+B+C = 180 </h2>
<h2>38°+75°+ X = 180°</h2>
<h2>113° + X = 180°</h2>
<h2>X = 180° -113</h2>
<h2>X = 67°</h2>
30-f+8f=30
30+7f=30
Move +30 to the right side. Sign changes from +30 to -30.
30-30+7f=30-30
7f=0
Divde by 7
7f/7=0/7
Cross out 7 and 7, divide by 7. Becomes 1*1*f=f
f=0
Answer: f=0
idk what kind of math problem but, if its just simple id us PEMDAS
Answer:
ok so you see the equation at the top... you are going to "plug in" the number in the "in" row to get the "out number
Step-by-step explanation:
example
in: 4
-2(-4)+1
8+1
9
so for the out row under -4 you would put 9
-2(-3)+1
6+1
7
so for the out row under 3 you would put 7
