You have an angle of elevation of 3 degrees and you're 2000 ft from base of 30 story building.
<span>Draw a picture of this. Then tan(3) = ht of bldg/2000 </span>
<span>I get a height of 104.82 ft rounded to 2 dp. </span>
<span>5. Ok. use the Pythagorean Theorem here to find the hypotenuse of the right triangle </span>
<span>hypt = sqrt(50^2 + 9^2) </span>
<span>Now sine of the angle of elevation is 50/hypt. = 0.984 or 0.98 to 2 dp.</span>
Answer:
yes
Step-by-step explanation:
Answer:0.52
Step-by-step explanation:
PEMDAS so, (10*1)=10 + (20*2)= 40+10= z= 50
Answer:
5+2(3x-4)-x
5+6x-8-x
it is simplified to -3+5x
