The missing angle would be :
90°[right angle] + 45° = 135
180 - 135 = 45°
I took 135 away from 180 because angles in a triangle always add up to 180°
Answer:
(-7, -8)
Step-by-step explanation:
To start we have to isolate a variable to get an equation for it.
Let's get an equation for x from the first equation:
x - 2y = 9
x = 2y + 9
Now that we know what x is in terms of y, lets plug it into our second equation:
3(2y + 9) - 5y = 19
6y + 27 - 5y = 19
y + 27 = 19
y = -8
Now that we know what y equals, let's plug it into our first equation and solve for x:
x - 2(-8) = 9
x + 16 = 9
x = -7
Now that we have x and y, we make our ordered pair, in terms of (x, y):
(-7, -8)
Hope this helps!
Answer:
Step-by-step explanation:
hello :
2(3/4x+7)-3(1/2x-5)=6/4x+14-3/2x+15
2(3/4x+7)-3(1/2x-5)= 29 because : 6/4=3/2
Answer:
2
Step-by-step explanation:
2*2=4
3*2=6
(im not gonna solve the last part)
so the second one is 2 times bigger
