Well I do not see the figure but I will assume it is a triangle. there are 3 angles in a triangle. Those 3 angles add up to 180. Since we know this, you can use the equation
angle1 + angle2 + angle3 = 180
we have 2 of the angles so with a little algebra we can solve for the last angle like this
180 - angle1 - angle2 = angle3
plug in 2 angles
180 - 50 - 90 = angle3
So answer is
angle3 = 40 degrees
Answer:
11. 16x +(9x+5)= 180
25x + 5 = 180
25x= 175
x= 7
If x is 7, then the top value is equal to the bottm one becuase they are vertical angles.
112 + 4y= 180
4y = 68
y= 17
Step-by-step explanation:
12. 6x - 11 + 2x - 9= 180
8x - 20= 180
8x= 200
x= 25
6(25) - 11= 139
20y + 19 = 139
20y = 120
y=6
Answer:
Step-by-step explanation:
if you have negative numbers of x (this means negative meters) then the equation transform them into negative yards.
then replace y by 40yd in the equation like
40 = 1.09x
x = 40/1.09 = 36.7 meters
so in a 40yd race, there are 36.7 meters.
Find out what angle it is. then add all sides abs subtract the total degrees and it’s your answer!
Answer:
Step-by-step explanation
By using midpoint formula :
(X,Y) = (X1+X2/2) ,(Y1+Y2/2)
