Answer:
45°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
60 + x + 87 + x + 57 = 180 add like terms
2x + 204 = 180 subtract 204 from both sides
2x = -24 divide both sides by 2
x = -12
angle A is x + 57 so if we replace A with the value we found
(-12) + 57 = 45°
Hey there!!
What is slope-intercept form :
... y = mx + b
( a ) Given :
... ( 2 , -2 ) and slope=1.4
... y = mx + b
... -2 = 2×1.4 + b
... -2 = 2.8 + b
... -4.8 = b
The slope-intercept form :
... y = 1.4x - 4.8
( b ) Given :
... ( -1 , 4 ) and slope = -3.
y = mx + b
... 4 = -3×-1 + b
... 4 = 3 + b
... 1 = b
The slope-intercept form :
... y = -3x + 1
Note :
( m = slope and b = y-intercept )
Hope my answer helps!!
