Answer:
∠ CAD = 32°
Step-by-step explanation:
The sum of the angles in Δ ABD = 180°, thus
∠ BAD + 100° + 48° = 180°
∠ BAD + 148° = 180° ( subtract 148° from both sides )
∠ BAD = 32°
Since AD bisects ∠ CAB , then
∠ CAD = ∠ BAD = 32°
a rectangluar rug has a length that is 3 times its width. The perimieter is 56 feet. what are the dimensions?
Answers
Answer:
7 x 21
Step-by-step explanation:
We can say that the dimensions are a and b. Since this is a rectangle, we know that the perimeter will be 2a + 2b. So our first equation is:
2a + 2b = 56.
They also tell us that the length is 3 times its width. So we can say this:
a = 3b.
Now we can substitute, and we can do the full problem with the given info:
2a + 2b = 56
a = 3b
2a = 6b
6b + 2b = 56
8b = 56
b = 7
Now that we know b, we can multiply it by 3 to get a:
b = 7
a = 3b
a = 21.
So our answer is:
a = 21
b = 7
Answer:
Dimensions:
7 x 21
Answer:
Width=7
Length=21
Step-by-step explanation:
p=56 feet
L=3W
P=2L + 2W
56=2(3W)+2W
56=6W+2W
56=8W
W=56/8 = 7 ⇒ Width=7
L=3W
L=3*7
L=21 feet ( length=21 feet)
check : p=2l+2w
P=2(21)+2(7)
p=42+14=56

The formula x + y = 180 can be used to find the degrees of supplementary angles, where x is the smaller angle. Find the domain and range of this solution
Answers
Answer:
Domain : 0° < x <90°
Range: 90° < y < 180°.
Step-by-step explanation:
When we have a function:
f(x) = y
the domain is the set of the possible values of x, and the range is the set of the possible values of y.
In this case we have:
x + y = 180°
such that x < y
Let's analyze the possible values of x.
The smallest possible value of x must be larger than 0°, as we are workin with suplementary angles.
Knowing this, we can find the maximum value for y:
0° + y = 180°
y = 180° is the maximum of the range.
Then we have:
0° < x
y < 180°
To find the other extreme, we can use the other relation:
x < y.
Then, we can impose that x = y (this value will not be either in the range nor the domain)
if x = y then:
x + y = x + x = 180
2*x = 180
x = 90°
This will be the maximum of the domain and the minimum of the range.
Then we have that the domain is:
0° < x <90°
And the range is:
90° < y < 180°.

If a+b+c=6,ab+bc+ca=11,then what is a3+b3+c3-3abc
Answers
(a+b+c)^3=a^3 +b^3+c^3-2(ab+ac+bc)
216=a^3+b^3+c^3-2(11)
a^3+b^3+c^3=238
but ıdk how can ı find -3abc :/
===============================================
Work Shown:
a+b+c = 6
(a+b+c)^2 = 6^2
(a+b+c)(a+b+c) = 36
a(a+b+c)+b(a+b+c)+c(a+b+c) = 36
a^2+ab+ca+ab+b^2+ca+bc+c^2 = 36
a^2+b^2+c^2+2ab+2bc+2ca = 36
a^2+b^2+c^2+2(ab+bc+ca) = 36
a^2+b^2+c^2+2*11 = 36
a^2+b^2+c^2+22 = 36
a^2+b^2+c^2 = 36-22
a^2+b^2+c^2 = 14
-----------------------
a^3+b^3+c^3-3abc = (a+b+c)*(a^2+b^2+c^2 - (ab+bc+ca) )
a^3+b^3+c^3-3abc = 6*(14 - 11)
a^3+b^3+c^3-3abc = 18
