Arman is building a bench. The bench comes out from the wall and there is a brace supporting the bench as shown in the figure below. The angle created between the wall and the brace is 52.6°. Which equation can be used to solve for the missing angle?

x+ 52.6°.+90=1801

Step-by-step explanation:

Hey!!!, we can imagine the right angles triangle formed. ok, let imagine it this way.

1. the bench comes out perpendicular to the wall

2. The brace forms an angel of 52.6

3. then the angle formed between the bench and the wall is  90°.

we know that the sum of angles in a triangles is  180°

let the third angle be x

Therefore the equation to find the missing angle is

x+ 52.6°.+90=1801

x+142.6=180

x=180-142.6

x=37.4°

step-by-step explanation: g=6

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
