8 0

Answer:

Step-by-step explanation:

7*(7 + x+1) = 6*(x + 5 + 6) {Intersecting secant theorem}

7 *(x + 8) = 6*(x + 11)

Distributive property,

7x + 56 = 6x + 66

Subtract 56 from both sides

7x = 6x + 66 - 56

7x = 6x + 10

Subtract 6x from both sides

7x - 6x = 10

x = 10

Find the area of the shaded sector of the circle

sweet-ann [11.9K]

Answer:

119.78 square m.

Step-by-step explanation:

$d = 28 \: m \implies \: r = 14 \: m \\ central \: \angle \:( \theta) \\ = 180 \:degree - 110 \degree \\ = 70 \degree \\ \\ area \: of \: sector \\ = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{70 \degree}{360 \degree} \times \frac{22}{7} \times {14}^{2} \\ \\ = \frac{7}{36} \times \frac{22}{7} \times 196 \\ \\ = \frac{7}{36} \times \frac{22}{1} \times 28 \\ \\ = \frac{7}{9} \times 22 \times 7 \\ \\ = \frac{1078}{9} \\ \\ = 119.777778 \\ \\ = 119.78 \: {m}^{2} \\$

Can somebody help with number 4 asap please

Mars2501 [29]

Answer:

x ≈ 41

Step-by-step explanation:

All the angles in a quadrilateral add together to equal 360°

So set up the equation:

a + b + c + d = 360°

Now fill in the values we know:

x + _ + 4x + 2x - 10 + 85 = 360

7x + 75 = 360

Now subtract both sides by 75:

7x + 75 - 75 = 360 - 75

7x = 285

Divide both sides by 7:

7x / 7 = 285 / 7

x = 40.714

Round:

x = 41

Now to check our answer, substitute 41 for x in the equation:

(41) + _ + 4(41) + 2(41) - 10 + 85

(41) + 164 + 82 - 10 + 85 = 362

The answer is close to 360, so we know it is correct
