Answer:
C. 5.35
Step-by-step explanation:
Because the midsegment is half of the base
All you have to do is divide the 10.7 by 2
 
        
                    
             
        
        
        
Answer:

or

Step-by-step explanation:
Divide the numerator and the denominator by the same number:

or
Multiply the numerator and the denominator by the same number:

 
        
                    
             
        
        
        
Answer:
75°
Step-by-step explanation:
1. Consider right triangle ABC. In this triangle
m∠C = 90º and CM - angle bisector.
If CM is angle C bisector, then
m∠ACM = m∠MCB = 45º
2. Consider triangle CMB. The sum of the measures of all interior angles of the triangle is always 180°, then
m∠MCB + m∠CBM + m∠BMC = 180°,
m∠BMC = 180° - 45° - 30°
m∠BMC = 105°
3. Angles AMC and BMC are supplementary angles, so
m∠AMC + m∠BMC = 180°
m∠AMC = 180° - 105°
m∠AMC = 75°
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Since the two triangles are similar, you can use proportions to solve for the value of 

Now, just multiply 4 and 12.

Then divide that by 3.
