Answer:
∠CBA = 132
Step-by-step explanation:
Bisectors split up an angle into two identical angles
Thus, 7x - 11 = 2x + 44
This is the equation we will use to solve for x
7x - 11 = 2x + 44
step 1 add 44 to each side
44 + 11 = 55
-11 + 11 cancels out
we now have 7x = 2x + 55
step 2 subtract 2x from each side
7x - 2x = 5x
2x - 2x cancels out
we now have 5x = 55
step 3 divide each side by 5
5x / 5 = x
55 / 5 = 11
we're left with x = 11
The question is asking for the measure of ∠CBA
To find the measure of ∠CBA we plug in 11 for x in one of the given expressions and multiply that by 2 ( this is because the two angles are identical so there is no need to find the measures of both because ∠CBD≅∠ABD )
7(11) - 11
7 * 11 = 77
77 - 11 = 66
66 * 2 = 132
372.634 is the answer to this equation
Answer:
Step-by-step explanation:
<em>L = 10 - 1.25t</em>
t = <em>1</em> ⇒ L = 10 - 1.25 = <em>8.75</em> inches
t = <em>2</em> ⇒ L = 10 - 1.25(2) = <em>7.5</em> inches
t = <em>3</em> ⇒ L = 10 - 1.25(3) =<em> 6.25</em> inches
(12+6) divided by (3+3) has a value of 3
Answer:
(a) 495, (b) 210
Step-by-step explanation:
Total number of persons = 12
number of openings = 8
number of women = 7
number of men = 12 - 7 = 5
(a) Number of ways to select the 8 persons
(b) Three are men
So, 3 men and 5 women
The number of ways are
