Check the picture below.

running a perpendicular line like so from the right-angle, makes three similar triangles, the large, containing the smaller ones, and a medium and a small one.  Now, using proportions, you can just  use there, the medium and smalle to get "x".

Find the area of the shape. Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and enter you
Len [333]

Answer:

Area of given figure = 37.68 unit²

Step-by-step explanation:

Given:

Radius of given shape = 4 unit

Angle = 270°

Value of π = 3.14

Find:

Area of given figure

Computation:

Area of given figure = [Ф/360][πr²]

Area of given figure = [270/360][(3.14)(4)²]

Area of given figure = [0.75][(3.14)16]

Area of given figure = [0.75][50.24]

Area of given figure = 37.68 unit²

katrin2010 [14]

Answer:

Plane: C) A flat surface that extends infinitively and has no depth; it has length and width

Perpendicular Lines: B) Two lines that intersect at 90° angles

Parallel Lines: E) Two lines that lie within the same plane and never intersect

Circle: D) A set of all points in a plane that are given distance from a plane

Angle: A) A figure consisting of two rays with a common endpoint

I hope this helps

this is 100% correct

Can someone check my math homework? Please I need it to be checked.
dmitriy555 [2]
I have to say this is wrong because you subtracted 3 and 3 is the variable term. So what you need to do is to add 9 to both side to get 3x by it self. Then divide by 3 and then x=6

1. Triangle ABC is similar to triangle JKL.
Fittoniya [83]
1. It's all about pattern matching, as a lot of math is.
Letter A corresponds to letter J, as both are first in the names of their respective triangles.
Letter B corresponds to letter K, as both are second in the triangle names. Likewise, letter C corresponds to letter L, as both are last.

Realizing this, it should not be too much of a stretch to see
   ∠B ⇒ ∠K
   ∠C ⇒ ∠L
   AC ⇒ JL
   BC ⇒ KL

2. Same deal. Match the patterns. Here, you're counting rings in the angle marks.
   1 ⇒ 1, so A ⇒ R
   2 ⇒ 2, so B ⇒ Q
since the figures are reportedly similar, you can continue in the same order to finish.
   ABCD ~ RQPS

3. The marked triangles cannot be similar. There are a number of ways to figure this. Basically, you want the ratios of sides to be the same for any similar triangles.

Here, you can eliminate the marked ones because the short side is too short relative to the others. (The average of the other two sides is double the short side in the similar triangles.)
