Answer:

x =25

<B = 65 degrees

<C = 50 degrees

Step-by-step explanation:

65 + (3x-10) +2x = 180

Add like terms:

55 +5x = 180

Subtract 55:

5x = 125

Divide by 5:

x = 25

Substitute for x and solve

Answer:

Step-by-step explanation:

AS we can see the lines are parallel so

2 ( 4x - 3) + 7(x + 3) = 180° ( being so - interior angles)

8x - 6° + 7x + 21° = 180°

15x + 15° = 180°

15x = 180° - 15°

15x = 165°

x = 165° / 15

Therefore x = 11°

Now

2 ( 4x - 3) = 2 ( 4 * 11° - 3°) = 2 ( 44 - 3)° = 2* 41 = 82°

7(x + 3 ) = 7 ( 11° + 3°) = 7 * 14 = 98°

Find the area of the shaded region. Round the the nearest tenth.

Brums [2.3K]

Answer:

226.084 sq.m.

Step-by-step explanation:

Radius of circle = 18.6 cm

Area of sector = $\frac{\theta}{360^{\circ} }\pi r^2$

Area of sector = $\frac{123}{360} \times 3.14 \times (18.6)^2$

Area of sector = $371.157 m^2$

Area of triangle = $\frac{1}{2} \times a \times b \times Sin x$

a = OA = radius = 18.6 cm

b = OB = radius = 18.6 cm

x =123 °

Substitute the values in the formula

Area of triangle = $\frac{1}{2} \times 18.6 \times 18.6 \times Sin 123$

Area of triangle = $145.073 m^2$

So, Area of shaded region = Area of sector - Area of triangle

= $371.157 m^2-145.073 m^2$

= $226.084 m^2$

Hence the area of the shaded region is 226.084 sq.m.
