Triangle sum and exterior angle theorem.

Mathematics
1 answer:
wlad13 [49]3 years ago
5 0

Did two of them for you as reference for the rest.

Explanation for #1

The sum of all the angles in a triangle is 180. Simply add the given angles. Take 180 and subtract the sum of the given angles

180 - (58 + 47) = 75

Missing angle is 75

Explanation for #4

A straight angle is 180 degrees. Same thing as the first: add the given angles then take 180 and subtract it.

Then take 180 <em>again </em>and subtract the answer you got from the first step.

180 - (21 + 34) = 125

180 - 125 = 55

The missing angle is 55

Workers on the assembly line produce 4x + 6 boats each day. Which expression shows how many boats they produced in 12 days?
vagabundo [1.1K]
The answer would be A. If 4x + 6 is the number of boats made in 1 day, then multiplying that by 12 would give us the number of boats made in 12 days so the equation would look like this:
12(4x + 6)

Graph B
lara [203]

Answer/Step-by-step explanation:

Slope (m) = rise/run

y-intercept (b) = starting value or the point on the y-axis where the line cuts across

✔️Slope (m) of skater 1:

Rise = 45

Run = 7.5

Slope (m) = 45/7.5 = 6

✔️ y-intercept (b) of Skater 1:

b = 0 (the y-axis is intercepted at 0)

✔️Skater 1 linear function in slope-intercept form, y = mx + b

Substitute m = 6 and b = 0 into y = mx + b

Linear function: y = 6x + 0

y = 6x

✔️Slope (m) of skater 2:

Rise = 30

Run = 15

Slope (m) = 30/15 = 2

✔️ y-intercept (b) of Skater 2:

b = 0 (the y-axis is intercepted at 0)

✔️Skater 2 linear function in slope-intercept form, y = mx + b

Substitute m = 2 and b = 0 into y = mx + b

Linear function: y = 2x + 0

y = 2x
