Answer:
m∠1 = 105°
m∠2 = 75°
Step-by-step explanation:
Lines a and b are parallel.
1. Angles 1 and 75° are the same side angles when two parallel lines a and b are cut by transversal t.
The same side angles add up to 180°, so
m∠1 + 75° = 180°
m∠1 = 180° - 75°
m∠1 = 105
2. Angles 2 and 1 are supplementary (add up to 180°), then
m∠1 + m∠2 = 180°
m∠2 = 180° - 105°
m∠2 = 75°
Answer:
Percentage of error by Clare is estimated as 4.1667 %.
Step-by-step explanation:
Height measured by Clare = 4 feet
Height measured by Doctor = 4 feet, 2 inches
Percentage error = ?
Percentage error = Difference/ Actual height *100
Percentage error = (2/ (4*12))*100
Percentage error = 4.1667 %
The accurate height is measured by Doctor, as he have more accurate measurement system.
<span>The correct answers are: #3) 72; #4) 40,320; #5) 90.
Explanation<span>:
#3) The number of possible choices are found by multiplying the choices of flavors and the choices of toppings:
6*12=72.
#4) The ordering of 8 cards is a permutation, given by 8!=40,320.
#5) This is a permutation of 10 objects taken 2 at a time:
P(10,2) = 10!/(10-2)!=10!/8!=90.</span></span>
Answer:
x = 22
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the interior angles
6x+1 = 79+ 2x+10
Combine like terms
6x+1 = 2x+89
Subtract 2x from each side
4x+1 = 89
Subtract 1 from each side
4x = 88
Divide by 4
4x/4 = 88/4
x = 22
