The figure to this problem is attached below. We know that angles ∠AEG and ∠GEC are supplementary, so:
∠AEG + ∠GEC = 180°
∠AEG = 8x°
∠GEC = (4x + 60)°
8x° + (4x + 60)° = 180°
(12x + 60)° = 180°
12x + 60 = 180
12x = 180 - 60
12x = 120
x = 10
∠AEG and ∠BEC are vertical angles, so they are congruent:
∠BEC = 8x°
∠BEC = 8(10)°
∠BEC = 80°
Answer:
y=-1/4x+1
Step-by-step explanation:
Hi there!
We're given the point (-8,3) and a slope of -1/4
lines are typically written in the formula y=mx+b, where m is the slope and b is the y intercept
as we are already given the slope, we can substitute its value into the equation
substitute -1/4 as m
y=-1/4x+b
now we need to find b
as the equation passes through the point (-8,3),we can use it to solve for b
substitute -8 as x and 3 as y
3=-1/4(-8)+b
multiply
3=2+b
subtract 2 from both sides
1=b
substitute 1 as b
y=-1/4x+1
The sum of all 3 angles in a triangle is 180
180-44=136
And you know that angle A is over 90 degrees so I believe it is 100 leaving angle b to be 36
100 feet left. A yard is 3 feet. Theres 5 yards in 8 pieces. 5*3=15 and 15*8=120. He uses 4 pieces that are 5 feet. 5*4=20. He uses 20 feet. 120-20= 100.
