Do this on paper, please.
First, rotate the larger rectangle about the origin so that it ends up being a vertically-oriented rectangle in the fourth quadrant (next to the smaller rectangle). What would you then have to do to this large, vertical rectangle so that it has the same size and shape as does the small vertical triangle?
Answer:
6:05
Step-by-step explanation:
.. .................
y = 2 ( x + 3/4 )^2 − 25 8
5/9
5 times 4= 20
12 times 3=36
20/36=5/9
Answers:
B = 50
a = 10.9
c = 17.0
================================================
Explanation:
This is a right triangle, so the acute angles are complementary, meaning they add to 90
B+40 = 90
B+40-40 = 90-40
B = 50
Also, because this is a right triangle, we can use trig ratios to compute the missing sides
tan(angle) = opposite/adjacent
tan(40) = a/13
a = 13*tan(40)
a = 10.908
a = 10.9
cos(angle) = adjacent/hypotenuse
cos(40) = 13/c
c*cos(40) = 13
c = 13/cos(40)
c = 17.0
note: make sure your calculator is in degree mode
