<span>More please help me solve the problem
The stars have different brightness. The brightest stars are Grade 1 and the least degree luimnoase stars 6. The brightness of the stars shrinks 2.5 times with the passing from one grade to another. Whenever the stars are brighter Grade 1, Grade 6 than the stars?</span>

Nothing else is given, so for the two triangles to be congruent, the only possible proof is the ASA theorem.
first pairs of angles: 2x+7=x+21 => x=14
second pairs of angles: 8y-4=4y+28 =>y=8
The two triangles share the same side PR
Based on the Angle-Side-Angle Triangle Congruence theorem, these two triangles are congruent with x=14, y=8
(2x+7) +(8y-4) +Q=180 =>85
        
             
        
        
        
Answer:
it will be 1/2
Step-by-step explanation:
because x×y={(6,2), (6, 8),(9,2), (9, 8)}
 
        
             
        
        
        
Answer:
Option B. 
Step-by-step explanation:
we know that
The area of a circle is equal to

we have

substitute

Remember that
 radians subtends the complete circle of area
 radians subtends the complete circle of area 
so
by proportion 
Find the area of the related sector for a central angle of  radians
 radians
Let
x------> the area of the related sector
