Elias is adding and . he finds the lcd to be 10t2 and uses multiplication to find equivalent expressions.

Step-by-step explanation:

So, we want to find the sum of the equivalent expression;

Since the two fractions are equivalent, we keep one denominator and add the numerators.

Regroup the terms in the numerator and add;

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
