Answer:
Step-by-step explanation:
The length of this triangle is 10 squares 
and the width is 4 squares 
The diagonals divide the rectangle into four triangles 
These traingles are isoceles
Each two triangles facing each others are identical 
<B = 90 degree 
B = alpha + Beta 
Let Beta be the angle next alpha 
The segment that is crossing Beta is its bisector since it perpendicular to the diagonals wich means that: 
Beta = 2x 
Then B = alpha + 2x 
90 = alpha +2x 
90-alpha = 2x 
x = (90-alpha)/2 
 
        
                    
             
        
        
        
<span>In circle F, what is the measure of ∠ CED ?
Given mAB = mBC = mCD = 36</span>°<span>
So
</span> ∠ CED =  1/2(mCD) = 1/2(36°) = 18°
Answer:
<span>B. 18</span>°<span>
---------------------------------------------------------------------
</span><span>What is the measure of ∠GET?
</span><span>
Given mTG = 70</span>°<span>
so 
<TNE = 1/2(</span>mTG) = 1/2(70°) = 35°
<span>
Right triangle NTG , < NTE = 90</span>° and <TNE = 35°
so <TEN = 90° - 35° = 55°
 <TEN = <GET = 55°
<span>
Answer
</span><span>A. 55</span>°
        
             
        
        
        
The total S divided by 8  was 5 more than the if the total S was divided by 10.
So we have S/8 +5 = S/10 and by switching the equation around you get S/10 = S/8+5
The correct answer is B.
