The correct question is
<span>Suppose you know that S angle and Y angle are complementary, and that angle S=5(angle Y)- 180 degrees. What is the value of angle Y?
we know that
</span>S angle and Y angle are complementary
so
S+Y=90-------> S=90-Y------> equation 1
and
S=5Y-180----> equation 2
equate equation 1 and equation 2
90-Y=5Y-180------> 5Y+Y=180+90-----> 6Y=270-----> Y=45°
S=5*45-180-----> S=45°
the answer is
Y=45°
Answer:
if the height is 5 then the answer is 1.2 but its possible i am wrong.
12 times 4 minus 3 because the 12 represents how much is in each of the 4 cases and you minus that by 3 and you get your answer
1. <span>The yz-plane is the plane x = 0. </span>
So, The general rule of reflection over the yz- plane is <span>(x,y,z) →(−x,y,z)
</span>
===========================================
<span>2. Applying the rule found in (1)
</span>
<span>the new points of the shape after this reflection will be
</span>
P(–1, 2, 0) ⇒⇒⇒ <span>P'(1, 2, 0)
</span>Y(2, 3, 0) <span>⇒⇒⇒ Y'(-2, 3, 0)
</span>
R(–3, 4, 0) ⇒⇒⇒ <span>R'(3, 4, 0)
</span>
A(–2, 1, 5) ⇒⇒⇒ A'(2, 1, 5)
=============================================
3. Applying the transformation rule <span>(x, y, z) → (x + 2, y + 4, z – 3)
</span>
<span />to the points from number 2
<span>P'(1, 2, 0) ⇒⇒⇒
P" (3 , 6 , -3 )
</span><span>Y'(-2, 3, 0) ⇒⇒⇒ Y" (0 , 7 , -3)
</span><span>R'(3, 4, 0) ⇒⇒⇒ R" ( 5 , 8 , -3)
</span>A'(2, 1, 5) ⇒⇒⇒ A" ( 4 , 5 , 2)
