Solve the equation. 9 = – x + 8

lord [1]

Answer:

x = - 1

Step-by-step explanation:

Given

9 = - x + 8 ( subtract 8 from both sides )

1 = - x ( multiply both sides by - 1 )

- 1 = x ⇒ x = - 1

In a circle with a diameter of 25.2 ft, an arc is intercepted by a central angle of 168º.

Rina8888 [55]

Answer:

$36.93\ ft$

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=\pi D$

we have

$D=25.2\ ft$

substitute

$C=25.2\pi\ ft$

step 2

we know that

The circumference of a circle subtends a central angle of 360 degrees

using proportion

Find out the arc length by a central angle of 168 degrees

$\frac{25.2\pi}{360}=\frac{x}{168}\\\\x=25.2\pi*168/360\\\\x=(25.2*3.14)*168/360\\\\x=36.93\ ft$

laws of Sines with find the angle. Find each measurement indicated. Round your answers to the nearest tenth. Show your work plea

Gwar [14]

Answer:

4. Z ≈ 46.1°

5. T ≈ 45.2°

6. F ≈ 15.0°

Step-by-step explanation:

We need to use the Law of Sines, which states that for a triangle with legnths a, b, and c and angles A, B, and C:

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Here, we can say that ZY = a = 30, X = A = 110, XY = b = 23, and Z = B. Plug these in to find Z:

$\frac{a}{sinA} =\frac{b}{sinB}$

$\frac{30}{sin(110)} =\frac{23}{sinZ}$

Solve for Z:

Z ≈ 46.1°

Use the Law of Sines as above.

$\frac{a}{sinA} =\frac{b}{sinB}$

$\frac{26}{sin(76)} =\frac{19}{sinT}$

Solve for T:

T ≈ 45.2°

Again, use the Law of Sines as before.

$\frac{a}{sinA} =\frac{b}{sinB}$

$\frac{29}{sin(137)} =\frac{11}{sinF}$

Solve for F:

F ≈ 15.0°
