Let us try and solve it analytically. We have that the side=x+3 together with the short side=s and the diagonal=x+4 satisfy the Pythagorean Theorem. Then we have that
. This yields
which yields s^2=2x+7, hence a) is the correct answer.
I found the accompanying picture of this word problem.
The circle was inscribe in the triangle. The area outside of the circle but inside the triangle is the shaded area.
True. The shaded area of the following shape can be found by subtracting the area of the circle from the area of the triangle.
1 and half hour
= 60 minutes+ 30 minutes
= 90 minutes
Now,
Uzanne need 15 minutes to do 10 problems
Uzanne need 1 minute to complete 10/15 problems
Uzanne need 90 minutes to do
= (10/15)*90
=(2/3)*90
=2*30
=60 problems

Answer:
a. sin 30* = sin 150*
b. sin 1* = sin 179*
a. cos 340* = cos 20*
b. cos 260* = cos 100*
Step-by-step explanation:
sine is symmetrical around x = 90*
cosine is symmetrical around x = 180*
* means degree sign of course.
