Answer:
100°
Step-by-step explanation:
the lower right angle is 180-149 = 31°
the sum of all three angles in a triangle is 180°.
so the solution is 180-31-49
Answer:
First, make the double negative a positive.
So, (-6/13) + (7/15)
Then multiply the numerator, 6×7=42
And denominator 13×15=195
42/195 simplify by dividing both by 3 so 14/65
So you know the merchant made a 15% profit on the pen, so she bought it for a cheaper price. To find the cost of the pen before you have to take the price now, $6.90 and times it by 85%. You do 85% because you subtract the 15% she saved from 100% and you get 85%. So 6.90x.85= 5.865 which rounds to $5.87
Answer:
I believe the answer is 45
Step-by-step explanation:
First do the parentheses: 12-2=10
Then do the exponent: 3^2=3*3=9
Next multiply 9 by 10: 9*10=90
Lastly divide 90 by 2: 90/2=45
