Answer:
∠x = 13.43°
Step-by-step explanation:
area ΔABC = 1/2 ( BD x AC) = 1/2 (22 x AC) = 42
22 x AC = 84 AC = 84/22 = 42/11 = 3.82
CD = BD - BC = 22 - 6 = 16
AD² = AC² + CD² = (3.82)² + 16² = 270.59
AD = 16.45
sin ∠x = AC / AD = 3.82 / 16.45 = 0.2322
∠x = 13.43°
Answer:
Step-by-step explanation:
We have that
A = 51°, b = 14, c = 6
step 1
find the value of a
Applying the law of cosines
a²=c²+b²-2*c*b*cos A
a²=6²+14²-2*6*14*cos 51-------> 126.27
a=11.2
we know that
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
we have
a=11.2
b=14
c=6
so
(a+b) > c-------------> (11.2+14)=25.2
25.2 > 6-----> is not correct
therefore
the answer is the option
a. No triangles possible
I don't know if i am right sorry if this is wrong
Answer:
The estimate volume of the box holding the tissue boxes V;
V = nv = 9×125
V = 1125 cubic inches
Attached is an image for further understanding of the question;
Step-by-step explanation:
Given;
Volume of each tissue box v = 125 cubic inches
Number of tissues n from the attached image;
n = 3×3 = 9 tissue boxes
The estimate volume of the box holding the tissue boxes V;
V = nv = 9×125
V = 1125 cubic inches
Answer:
36
Step-by-step explanation:
Answer: {xI x ∈ R, 19 < x < 32}
Step-by-step explanation:
This notation is:
{xI condition1, condition2, ...}
The first condition is:
From what set we take the values of x?
From the set of real numbers.
x ∈ R
The other conditions are the limitations that we have for x, in this case:
19 < x < 32
Then we can write this as:
{xI x ∈ R, 19 < x < 32}
