An engineer needs to find the length of a beam to support the beam holding the wall. If the two beams are perpendicular to one another, and a=5 m and b=3 m, find z. Give your answer to one decimal place.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

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)
