Answer:
The triangle is not a Right Triangle because the two acute angles aren't exactly 45 degrees.
Step-by-step explanation:
 
        
             
        
        
        
FOR Y 
opposite angles - equal 
angles in a quadrilateral are 360 degrees 
68 + 68 = 136 
360 - 136 = 224
224/2 = 112 degrees
angles on a straight line = 180 degrees 
180 - 112 = 68 
Y = 68
FOR X 
angles on a straight line are 180 degrees 
180 - 68 = 112 degrees
X=112 degrees
        
             
        
        
        
Slope intercept form: y = mx + b
mx = slope
b = y-intercept
We know the y intercept is 0, so nothing will be written there.
To find the slope of this line, we can use the slope formula.

We'll use the points (1, 0) and (3, 1) to find the slope.
Now we can just plug these values into the equation to find the slope.
1 - 0 / 3 - 1
1 / 2
The slope of the line is 1/2, or 0.5.
The slope-intercept form of this line can be written as:
y = 0.5x
 
        
             
        
        
        
For number one you should get 6√3 
        
             
        
        
        
From the given figure ,
RECA is a quadrilateral 
RC divides it into two parts
From the triangles , ∆REC and ∆RAC
RE = RA (Given)
angle CRE = angle CRA (Given)
RC = RC (Common side)
Therefore, ∆REC is Congruent to ∆RAC
∆REC =~ ∆RAC by SAS Property
⇛CE = CA (Congruent parts in a congruent triangles)
Hence , Proved
<em>Additional</em><em> comment</em><em>:</em><em>-</em>
SAS property:-
"The two sides and included angle of one triangle are equal to the two sides and included angle then the two triangles are Congruent and this property is called SAS Property (Side -Angle-Side)
