Answer:
x = 17
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
3x + 2x - 5 + 6x - 2 = 180
11x - 7 = 180 ( add 7 to both sides )
11x = 187 ( divide both sides by 11 )
x = 17

Find the measure of CB.
Answer:
I'm Pretty Sure Its 40.
Step-by-step explanation:
Answer:
CB = 20.
Step-by-step explanation:
If the triangle is Isosceles, assuming that <D = <B according to the markings, CB must be 20 since 32 is the greatest side and therefore the hypotenuse, 20 is the smaller side and therefore either opposite or adjacent. Given that two sides must be the same, since CB is opposite of angle D which is congruent to angle B, CB = side opposite of angle B = 20.

Emily has sent 28 text messages so far this week
that is 20 % of the total number of text messages she is allowed in one week
what is the total number of text messages emily can send in one week?
Divide the amount she sent by the percentage she sent:
28/0.20 = 140
She can send 140 in one week.

Answer:
x = 4
Step-by-step explanation:
I like to put these in the form f(x) = 0. We can do that by subtracting the right side. Common factors can be cancelled from numerator and denominator, provided they are not zero.
[tex]\dfrac{7}{x+3}+\dfrac{3}{x-3}-\dfrac{x}{x-3}=0\\\\ \dfrac{7(x-3)+(x+3)(3-x)}{(x+3)(x-3)}=0\\\\\dfrac{(x-3)(4-x)}{(x-3)(x+3)}=0\\\\ \dfrac{4-x}{x+3}=0\qquad x\ne3\\\\x=4 \qquad\text{equate the numerator to zero, add $x$}[/tex]
_____
If you leave the numerator as (x-3)(4-x), then there are two values of x that make it zero. Because x=3 makes the equation "undefined", it cannot be considered to be a solution.

Solve for x. Round answer to the nearest tenth (0.1).
Answer:
x = 9.9
Step-by-step explanation:
This is a isosceles triangle, with sides measurements (1 , 1 , √2), and the angles being (45° - 45° - 90°). Note that the side measurements of 1 is opposite of that of a 45°, while the measurement of √2 is opposite of that of 90°.
In this case, multiply. The side measurement of 1 has 7.
1 x 7 = 7
In the same, you must multiply 7 with √2
x = 7 * √2 = 7√2.
√2 = ~1.414
7 x 1.414 = 9.898
Round to the nearest tenth:
9.898 rounded to the nearest tenth = 9.9
x = 9.9
~
Answer:
9.9 is your answer
Step-by-step explanation:
by using Pythagoras law
p²+b²=h²
7²+7²=x²
x=√{2×49)=7√2or 9.9 is your answer
Find the base of a triangle whose altitude is 12 cm and area is 96 cm
Given:
Altitude of a triangle = 12 cm
Area of the triangle = 96 sq. cm
To find:
The base of the triangle.
Solution:
The area of a triangle is
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Putting Area = 96 and height = 12, we get
[tex]96=\dfrac{1}{2}\times base\times 12[/tex]
[tex]96=6\times base[/tex]
Divide both sides by 6.
[tex]\dfrac{96}{6}=base[/tex]
[tex]16=base[/tex]
Therefore, the base of the triangle is 16 cm.

Mrs. Johnson gets her morning coffee. She can't decide which size to order. Which size is the better buy? Explain.
Small- 12 oz for $3.95
Medium- 16 oz for $4.25
Large- 20 oz for $4.55
Answer:
large
Step-by-step explanation:
3.95 divided by 12 = 0.33
4.25 divided by 16 = 0.27
4.55 divided by 20 = 0.2275
the 20oz is the least unit price
what is the measure of the base angle,x, of the isosceles triangle shown below? round your answer to the nearest tenth of a degree.
Answer:
x ≈ 49.7°
Step-by-step explanation:
Since, the given triangle is an isosceles triangle,
Two sides having measure 17 units are equal.
Opposite angles of these equal sides will be equal.
Measure of the third angle = 180° - (x + x)°
By sine rule,
[tex]\frac{\text{sinx}}{17}=\frac{\text{sin}(180-2x)}{22}[/tex]
[tex]\frac{\text{sinx}}{17}=\frac{\text{sin}(2x)}{22}[/tex] [Since, sin(180 - θ) = sinθ]
[tex]\frac{\text{sinx}}{17}=\frac{2(\text{sin}x)(\text{cos}x)}{22}[/tex]
[tex]\frac{\text{sinx}}{17}=\frac{(\text{sin}x)(\text{cos}x)}{11}[/tex]
[tex]\frac{1}{17}=\frac{(\text{cos}x)}{11}[/tex]
cos(x) = [tex]\frac{11}{17}[/tex]
x = 49.68°
x ≈ 49.7°
