Answer:
1. They consist primarily of variables.
2. They are often called formulas.
4. They often describe real-world relationships.
Answer:
Statement 1. P
Reason 1. Theorem: The measure of an external angle of a triangle is equal to the sum of the measures of the remote interior angles.
Statement 2. 132 = 3x + 54
Statement 3. x = 26
To find the hypotenuse of the triangle
you use the length of the legs
Plug it into the Pythagorean Theorem
so


is one of the legs
and

is the other leg
then

is the hypothenuse
Answer:
measure of angle ABC is 6 degree.
Step-by-step explanation:
After you found x, you'll plug it in the equation of the angle it's asking for.
Measure of angle ABD, and you know measure of angle ABC = 4x-1.
4(1)-1 = 4-1 = 3
Measure of angle CBD = 2x+1.
2(1) +1 = 3
Measure of angle ABC is ABD + CBD
3 + 3 = 6
