Answer:

11.75

Step-by-step explanation:

Interior angles in a quadrilateral sum to 360.

Opposite angles in a parallelogram are the same.

360=118+118+(4x+15)+(4x+15)

= 236 + 8x + 30

= 266 + 8x

8x = 360 - 266 = 94

x=94/8 = 11.75

Answer:

x=11.75

If the answer is 11.75, move to L.

Step-by-step explanation:

The sum of all angles in this parallelogram is 360°. And angles which are vertical are the same.

118+118= 236

236+2(4x+15)=360

236+8x+30=360

8x+266=360

8x=94

x=11.75

Find the area of the unshaded reason for these two problems​
Taya2010 [7]

9514 1404 393

Answer:

  a) 96 m²

  b) 26,000 ft²

Step-by-step explanation:

The area of the unshaded region is the difference between the overall area of the rectangle and the area of the shaded region. It can also be found directly using the dimensions of the unshaded region.

a) We have the height of the right triangle, but need to know its base. The Pythagorean theorem can help with that. Let the base of the triangle be represented by x. Then ...

  x² +16² = 20²

  x² = 400 -256 = 144

  x = √144 = 12

The area of the unshaded triangle is given by the formula ...

  A = (1/2)bh

  A = (1/2)(12)(16) = 96 . . . . square meters

__

b) The shaded area at upper left is a square 100 ft on a side. Its area is ...

  A = s² = (100 ft)² = 10,000 ft²

The shaded area at upper right is a triangle with base and height 120 ft and 150 ft. Its area is ...

  A = (1/2)bh = (1/2)(120 ft)(150 ft) = 9,000 ft²

The area of the overall rectangle is ...

  A = LW = (300 ft)(150 ft) = 45,000 ft²

So, the unshaded area is ...

  unshaded area = overall area - left shaded area - right shaded area

  unshaded area = 45,000 ft² -10,000 ft² -9,000 ft² = 26,000 ft²

If m ABC = 122°, and m<br> then m
ANTONII [103]

Answer:

m < DBC = 51

Step-by-step explanation:

Looking at the picture, we know <ABD and <DBC make up <ABC. Knowing this, we can set up an equation like so, plug in the known values, and solve to find m<DBC:

m
