You'd have to provide the pattern...
All of the angles in a triangle equal 180° so if the first 2 angles are 60°, combined that equal 120°, leaving 60° left. X= 60°
Answer:
y = -1x + 13
Step-by-step explanation:
y = -1x + b
5 = -1(8) + b
5 = -8 + b
13 = b
Answer:
Step-by-step explanation:
area = length x breadth
length = 5 inches greater than width = 5+x
width = x
area = (5+x) x
104 = (5+x) x
104 = 5x + x²
x²+5x-104 =0
looking for two numbers that when you multiply gives 104, and adding it gives +5
the numbers is 13 and 8 (-13, +5)
x²+5x-13x-104 =0
x(x+5)-13(x+5) = 0
(x+5)(x-13)=0
x+5 =0 x-13 =0
x = -5, x=13
x= -5, 13
the width is either -5 or 13 inches
the length = (5+x) = (5+(-5)) = 5-5 =0
(5+x) = (5+13) = 5+13 = 18
lenth is 0 or 18 inches
