Answer: disagree its backwards
Step-by-step explanation: the x intercept always comes first so its actually (-4,2)
If you have a calculator, you can use the inverse cos " cos⁻¹ " key. Many upper level books write that as Arccos so as not to confuse you with a negative exponent. We do that because if you take the cosine of any angle, and then the inverse cosine of any angle, it leads you back to the original angle. Think of it as a big "UNDO" button.
To one decimal place, that result is 61.6 degrees.
Answer:
Step-by-step explanation:
let base be x and height be 3x
we know area of parallelogram is
base*height
ie x*3x=675
3x^2=675
x^2=675/3
x^2=225
x= square root of 225
x=15
therefore base =15
height = 45
Answer:
The third side can be any length as long as it is greater than 4 in and less than 26 in
Step-by-step explanation:
we know that
The<u> Triangle Inequality Theorem</u>, states that The sum of the lengths of any two sides of a triangle is greater than the length of the third side
Let
x ----> the length of the third side
Applying the triangle inequality theorem
1) 11+15 > x
26 > x
rewrite
x < 26 in
2) 11+x > 15
x> 15-11
x > 4 in
therefore
Aziza's claim is incomplete
The third side can be any length as long as it is greater than 4 in and less than 26 in
