The complete question in the attached figure N 1
see the attached figure N 2 to better understand the problem
we know that
sin 26°=y/14-------> y=14*sin 26°------> y=6.14 ft
the answer is<span>
The height of the ramp is about 6.14 ft</span>
<u>1 = 62°</u> ( Vertically Opposite Angles )
<u>10 = 62°</u> ( Corresponding Angles )
<u>9 = 10 = 62°</u> ( Vertically Opposite Angles )
<u>6 = 95°</u> ( Vertically Opposite Angles )
<u>7 = 180° - 95° = 85°</u> ( Linear Pair )
<u>8 = 7 = 85°</u> ( Vertically Opposite Angles )
<u>5 = 8 = 85°</u> ( Corresponding Angles )
<u>3 = 5 = 85°</u> ( Vertically Opposite Angles )
4 = 180° - ( 9 + 7 )
4 = 180° - ( 62° + 85° )
4 = 180° - 147°
<u>4 = 33°</u> ( Angle Sum Property )
<u>2 = 4 = 33°</u> ( Vertically Opposite Angles )
Answer:
30 are present and 10 are absent
Step-by-step explanation:
75% of 40 is 30
Therefore 30 pupils are present
And 10 pupils are absent
