Answer:
m∠A = 20°
Step-by-step explanation:
Given that the sum of the angles of any triangle is 180°, adding the expressions of each angle and setting them equal to 180° will give the value of 'x' and allow you to evaluate the angles.
2x + 5x + 11x = 180
18x = 180
18x/18 = 180/18 or x = 10
m∠A = 2x or 2(10) = 20°
m∠B = 5x or 5(10) = 50°
m∠C = 11x or 11(10) = 110°
Out of the choices given, the only one that is true is that m∠A = 20°.
Answer:
13×1/4
Step-by-step explanation:
turn into improper fraction
Answer:
2.5
Step-by-step explanation:
Substitute the given value of x into the first equation
To solve for x distribute 3 though the parentheses
Collect like terms
Move the constant to the right-hand side and change its sign
Add the numbers
Divide both sides of the equation by 13
Now, Substitute the given value of x into the second equation
Plug in the value of x in the equation i.e. 1
Any number multiplied by 1 results in number itself
Calculate the difference
The possible solution of the system is the ordered pair (x,y)
Answer:
$2625
Step-by-step explanation:
A commission rate of 21% means you get a commission that is 21% of the value of the sale. To find this amount, multiply the value of the sale by 21%. Of course, you know that 21% = 21/100 = 0.21.
21% · $12,500 = $2,625
You earn $2625 on the sale.
