Answer:

x=66°

Step-by-step explanation:

We know that the total angle measure in a triangle is always 180°, so first we need to find the angle value of BAC. They give us a straight line aligning with this angle and measure of 98° for the angle DAB (which is forming other part of line) and a line is 180° so we subtract and find that angle BAC is 82°.

Now that we know the angle measure of 2 angles in the triangle, we add them up and get 114°. Now we subtract this from 180° and get 66°, which is the measure of x.

Please help with this precalc!!! i desperately need help
Paladinen [302]

Step-by-step explanation:

4 is the A or Ampltiude

To find the period set it equal to 2 pi/B

\frac{2\pi}{b}  =  \frac{6}{1}

\frac{b}{2\pi}  =  \frac{1}{6}

b=

\frac{2\pi}{6}

b=

\frac{\pi}{3}

There is no phase shift

The midline or d or vertical shift is 1.

Our equation for 8 is

4 \sin( \frac{\pi}{6} x)  + 1

9.Use sin function. The a value is 2 or -2 your choice.

Set up the period equal to the equation

\frac{2\pi}{b}  =  \frac{\pi}{3}

\frac{b}{2\pi}  =  \frac{3}{\pi}

b =  \frac{3}{\pi}  \times 2\pi

Which equal 6.

B=6

There is no C and the D and Vertical Shift is 1.

Our equation is

2 \sin(6x)  + 1

Find the angle between the given vector in degrees. u=<6, 4>, v=<7, 5> HELPPPPPPPPPP
Paladinen [302]

Recall that

\vec a\cdot\vec b=\|\vec a\|\|\vec b\|\cos\theta

where \theta is the angle between the vectors \vec a,\vec b whose magnitudes are \|\vec a\|,\|\vec b\|, respectively.

We have

\langle6,4\rangle\cdot\langle7,5\rangle=\sqrt{6^2+4^2}\sqrt{7^2+5^2}\cos\theta

\cos\theta=\dfrac{31}{\sqrt{962}}\implies\theta\approx88.2^\circ

The length of a rectangle is twice its breadth. If its length is decreased half of the 10 cm and the breadth is increased by hal
Leto [7]

Since the length of this rectangle is twice its breadth, the length is equal to 40 cm.

<h3>How to calculate the area of a rectangle?</h3>

Mathematically, the area of a rectangle can be calculated by using this formula:

Area = Length × Width

Based on the information provided, we have:

  • Its length is decreased half of the 10 cm ⇒ (length - 5)
  • Its breadth is increased by half of the 10 cm ⇒ (breadth + 5)
  • Its area is increased by 75 cm ⇒ (area + 5)

Substituting the parameters into the formula, we have:

LB + 75 = (L - 5)(B + 5)

2B² + 75 = (2B - 5)(2B + 5)

2B² + 75 = 2B(B + 5) - 5(B + 5)

2B² + 75 = 2B² + 10B - 5B - 25

5B = 75 + 25

5B = 100

B = 100/20

B = 20 cm.

For the length, we have:

L = 2B

L = 2 × 20

L = 40 cm.
