Can someone please help me it’s timing me I’m confused

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°

Step-by-step explanation:

The number of columns in the first matrix must equal to the number of rows in the second for multiplication to be possible.

Here first matrix has 3 columns and second one has 3 rows so POSSIBLE.

[ -8 2 2]    { 3 }

                [ 0 ]

                [ -3]

=  -8*3  + 2*0 + 2 * -3 = [-30]  <-------- Answer.

Note  a  1*3 matrix multiplied by a 1*3 matrix gives a 1*1 result.

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.

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.

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.

Translate Aabc to the left 10 units and down 10 units.

Step-by-step explanation:

you pick a single point on the triangle that is being transformed (in this cause I chose .B)

you count the difference between the points on the x-axis (10)

then do the same on the x-axis (also 10)

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

Answer:

Step-by-step explanation:

Use the identity: a² - b² = (a + b)(a- b)

4 - 9w² = 2² - (3w²)
