You have to multiply the fraction by the parenthesis and then combine like terms and so on
Answer:
if its one of the options and you have the same diagram as me the answer would be 150 the circle adds up to 360 in total so if angle 1 is 100 then angle 2 has to be 80 because a line adds up to 180 since the angle 3 is 30 you just add up 180 and 30 which would be 210 you just subtract that from 360 and you are left with 150
(again only if you have the same diagram as me because i had the same question but with 150 instead or 110)
Step-by-step explanation:
(x+7) (x-7)
Because: the difference of two squares.
By just taking a glimpse at the problem, you can immediately mentally determine whether 125 x 0.9 is greater than 125. You are multiplying 125 by a positive number that is greater than 1, therefore the value will increase. This is how anyone can mentally envision 125 x 0.9 to be greater than 125.
Answer: 4 / 5
Step-by-step explanation: 1) For a right triangle, the ratio sine is defined as:
sin(x) = opposite-leg / hypotenuse
2) x is the angle. In this case: A
3) As per the figure, the opposite leg to tha angle A measures 28
4) As per the figure, the hypotenuse measures 35
5) Calculations:
sin(A) = 28 / 35
Simplify dividing both numerator and denominator by 7 => 28/35 = 4/5
