In DCAB, If DB=38, What is DC? 38 45 52 112

dedylja [7]

Answer:

C. 52°

Step-by-step explanation:

In ∆CAB, m<A = right angle = 90°

m<B = 38°

m<C + m<A + m<B = 180° (sum of ∆)

m<C + 90° + 38° = 180° (substitution)

m<C + 128 = 180

m<C = 180 - 128 (subtraction property of equality)

m<C = 52°

Quadrilateral OPQR is inscribed in a circle as shown below...

kipiarov [429]

We can use the fact that a cyclic quadrilateral (i.e. a quadrilateral inscribed in a circle) has the opposite angles supplementary, therefore
2x+(2x+4) = 180
Solving for x:
4x+4=180
4x=180-4=176
x=176/4=44 °
=>
angle O = 2x = 88 °
angle Q=180-O=180-88 = 92 °

Similarly,
(3y+8)+y= 180
=> y=43 °
=>
P=y=43 °
R=180-43=137 °

Find the area of each figure. Use 3.14 for pi.

Alik [6]

Answer:

208m²

Step-by-step explanation:

Okay, so you can split this abomination into a rectangle, another rectangle, and a square, so we're going to start with the rectangle to the far left:

The formula for the area of a rectangle or square is length x width, so we just have to plug:

4 x 8 = 32

Now we do the next rectangle, but we have to figure out the length first, so:

4 + 4 = 8

Now we plug:

8 x 4 = 32 (I now realize that the rectangles are even and we could've just multiplied the first one by two, but it's always good to check)

Now we do the square:

12 x 12 = 144

Now we add it all together:

32 + 32 + 144 = 208

So the area of the figure is 208m²

if this is wrong, let me know so I can fix it

hope this helps:)

Colby wants to set square tiles on the top of a wooden box. The top of the box is a rectangle7 1/2 inches long and 5 1/2 inches

Nostrana [21]

Multiply 7 1/2 by 5 1/2 and get 41 and 1/4

now divide 41 1/4 by 1/2 and get 83..

83 would be your answer(I got a little confused so this might be wrong D:)
