Answer:

m∠1  = 67.4°      m∠2 = 104.5°

Step-by-step explanation:

17.3 + m∠2 = 121.8

m∠2 = 104.5°

m∠1 + 37.1 = m∠2 = 104.5

m∠1  = 67.4°

Answer:

Angle 1 = 102

Angle 2 = 40.9

Step-by-step explanation:

1)\ 180 - 121.8 = 58.2

2)\ angle\ 2 = 58.2 - 17.3 = 40.9

3)\ angle\ 1 = 180 - 40.9 - 37.1 = 102

Find the value of x.
Novay_Z [31]

Answer:

x = 50°

Step-by-step explanation:

Angles in a quadrilateral add to 360°

First work out the interior missing angle

360° - ( 40° + 80° + 110° ) = 130°

Angles on a straight line add to 180° so

180° - 130° = 50°

Find an equation of the circle that has center(-3,4) and passes through(1,-2)
Yuliya22 [10]

Answer:

  (x +3)^2 +(y -4)^2 = 52

Step-by-step explanation:

The standard form equation of a circle with center (h, k) and radius r is ...

  (x -h)^2 +(y -k)^2 = r^2

We are given the value of (h, k), and we can find the value of r^2. Using the values of h and k, our equation is ...

  (x +3)^2 +(y -4)^2 = r^2

Since we know this equation is satisfied by the point (1, -2), we can use this point in the equation to find r^2:

  (1 +3)^2 +(-2 -4)^2 = r^2

  16 +36 = r^2 = 52

The equation of the circle is ...

  (x +3)^2 +(y -4)^2 = 52

Answer:

101.5yd by 101.5yd size of wood

Step-by-step explanation:

Divide the ramp into its constituent shapes:

2 triangles( 3yd by 4.5yd by 5yd)

1st rectangle (the back) 3yd by 11yd

2nd rectangle (the front) 11yd by 5yd

  • Find the area of the shapes

Area of triangles = 2 * (1/2*b*h) = 2 * (0.5 * 4.5 * 3) = 2 * 6.75 yd² = 13.5yd²

Area of back rectangle= 3 * 11 = 33yd²

Area of front rectangle = 11 * 5 = 55yd²

  • Find the sum of the areas

13.5yd² + 33yd² + 55yd² = 101.5yd²
