The other angle is 190-7x.
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
Let A be the third angle.

A = 180 - (3x - 20) - (4x + 10) = 190 - 7x
Answer:
(2, 3)
Step-by-step explanation:
2x + 5y = 19
5y = -2x + 19
y = 
P(abscissa, ordinate)
P(x, 1.5x)
P(2, 3)
3 = 15/5
3 = 3
Answer:
n= 4.7
Step-by-step explanation:
n+−3.66=1.04
n−3.66=1.04
Step 2: Add 3.66 to both sides.
n−3.66+3.66=1.04+3.66
n=4.7
Answer:
n=4.7
