Answer:
x = 35°
Step-by-step explanation:
The question is as following
cos x = sin(20 + x)° and 0° < x < 90° , find X?
==============================================
cos x = sin(20 + x)°
sin and cos are co-functions,
which means that: cos x = cos [90 - (20 + x)]
∴ x = 70 - x
∴ 2x = 70
∴ x = 35°
======================
Note: cos θ = sin ( 90 - θ )
The first composite shape we would need to find is the rectangle. We would use the formula length multiplied by width. The second composite shape is a hemisphere. The area of a hemisphere is Pi multiplied by the radius squared and then divide it by 2. To find the area of both of these figures, add up the area for each one and then you will get the
area of both.

Answer:
⠀
Step-by-step explanation:
The triangle having two sides equal along with one different side is called an isosceles triangle.
⠀
- So, Let us assume the other sides (two equal sides) of the isosceles triangle as x. As the different side is already given in the question.
⠀
We know that,
- The sum of all angles of a triangle is 180°
⠀
So, According to the question :
⠀
⠀
⠀
⠀
⠀
⠀
⠀
Therefore,
- The measure of the two other angles of the isosceles triangle are 71° and 71°.
Answer:
You can't have a single answer.
Step-by-step explanation:
An indiviual equation can't be solved if it has 2 variables.
You can, however, graph it.
The line will create all the possible sets of answers for the problem.
