Answer:
8 is your answer for x
Step-by-step explanation:
Note that this is an equilateral triangle, meaning that all of the sides are congruent. This means that all the angel measurements are congruent.
First, divide 180 with 3 (3 because there are 3 angles)
180/3 = 60
Each angle must equal 60. You are solving for x. Set the expression with x as the variable equal to 60
7x + 4 = 60
Isolate the x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 4 from both sides.
7x + 4 (-4) = 60 (-4)
7x = 60 - 4
7x = 56
Next, divide 7 from both sides.
(7x)/7 = (56)/7
x = 56/7
x = 8
8 is your answer for x.

Answer:
The difference is 85 ft.
Step-by-step explanation:
Elevation 1: 50 ft
Elevation 2: -35 ft
Difference = Elevation 1 - Elevation 2
Difference = 50 - (-35)
I can simplify this expression, as subtracting a negative number is the same as adding a positive number:
Difference = 50 + 35
Difference = 85
Answer: The difference is 85 ft.
Answer:
0.7938
Step-by-step explanation:
z1 = (125-100)/15 = 1.667
P( < 125) = 0.9522
z2 = (85-100)/15 = -1
P( > 85) = 0.8413
0.9522 + 0.8413 - 1 = 0.7935
