An engineer stands 30 ft. from a building and notes a 55 degree angle of elevation to the top of the building. How high is the b

alexdok [17]

<h3>Answer: 42.8 feet</h3>

Work Shown:

h = height of the building

h is opposite the reference angle (55)

the adjacent side is 30 feet

tan(angle) = opposite/adjacent

tan(55) = h/30

h = 30*tan(55)

h = 42.84444 which is approximate

h = 42.8 feet

Devaughn is 8 years older than Sydney. The sum of their ages is 64. What is Sydney's age?

Zigmanuir [339]

Answer:

Sydney's age is 28

Step-by-step explanation:

Let Devaughn be D

And Sydney be S

D=S+8..... equation 1

D+S=64...... equation 2

Substitute equation 1 to equation 2

S+8+S=64

2S+8=64

2S=64-8

2S=56

S=56/2

S=28
