16,30.34
Step-by-step explanation:
Answer:
x = 13
39° and 51°
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
This is a right angle triangle, so one side has a size of 90 degrees.
3x + 4x - 1 + 90 = 180
7x + 89 = 180
7x = 91
x = 91/7
x = 13
Put x as 13 to work out the size of the angles.
3(13) = 39
4(13) - 1
52 - 1 = 51
( 1 ,2) is in first quadrant
(-1,2) is in second
(-1,-2) is in the third
( 1, -2) is in 4th quadrant
Answer:
Step-by-step explanation:
Note that if it has a y- intercept of 20, this means that when x = 0 , y = 20
Find the table which shows that :)
