The answer is D) Seventh and eighth grade students at the school preferred an eagle mascot.
This is because both Tiger and Eagle had 40 votes, so it couldn't be A) or B), as they both had the same number of votes. It also couldn't be C) because more fifth and sixth grade students voted for tiger than eagle. It could only be D) as more seventh and eighth grade students DID actually vote for the eagle mascot rather than the tiger mascot.
Answer:
55
Step-by-step explanation:
In a triangle all the angles = 180 degrees
That means: x + y + 90 = 180
x + y = 180 - 90 = 90
35 + y = 90
y = 90 - 35
y = 55 degrees
Answer:
C. 45 degree angle
Step-by-step explanation:
let AB be the height of the wall and CD be the height of boy
with BC as distance between them.
we have AE = AB-BE = 3.64-1.54 = 2.1m
and ED = BC = 2.1m
in triangle AED, we have
tanФ = P/B = 2.1/2.1
tanФ = 1
∴ Ф = 45°
Hence the sun is elevated at an angle of 45 °.
