Aladder that is 32 ft long leans against a building. the angle of elevation of the ladder is 70 degrees

how high off the ground is the top of the

a.20ft
b.30ft
c.26ft
d.39ft

B. 30 ft

Step-by-step explanation:

The ladder is 32 ft long

The angle of elevation of the ladder is 70°

The height (h) of the top of the ladder to the ground is what we are to find.

= sin 70°

h = 32 × sin 70° = 30.07016387 or 30 ft (rounded off to nearest feet)

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
