find the value of x in each triangle. show your work on a separate piece of paper
Answers
Answer:
x = 70°
Step-by-step explanation:
the interior angle which is supplemental to 140° is 40°
the sum of the interior angles of any triangle is 180°
so:
180° = 40° + 2x
subtract 40° from each side of the equation:
2x = 140°
x = 70°

Which is a zero of the function f(x) = 2x – 6?
2
-3
-6
3
Answers
Answer and explanation:
The answer is actually -3. We already know f(x)/y is equal to 0, so the equation is then simplified to 0 = 2x - 6. You do inverse operation, so then -6 = 2x. Then -6 divided by 2 is -3. So -3 = x. Therefore, the zero of the function f(x) = 2x – 6 is -3.

A farmer has a field in the shape of a semicircle of diameter 50 m. First,
calculate the length of the semicircle to 1 decimal place.
50 m
Answers
Answer:
157.1 m
Step-by-step explanation:
Here, we want to calculate the length of the semi-circle
This simply refers to the circumference of the semi-circle
Mathematically, the circumference is half that of a full circle
The circumference of a full circle is;
C = pi * d
For half circle or semi-circle;
It is ;
C = (pi * d)/2
D = 50 m
The circumference is thus;
C = 50 * 3.142
C = 157.1 m

Cot 1/2x-1=0
Add 1 to both sides
Cot 1/2x = 0+1
Cot 1/2x = 1
1/tan1/2x = 1
Tan 1/2x = 1
1/2x = arctan1

2) Simplify 3² to 9.
[tex]( {x}^{2} - 9)(3x + 2)[/tex]
3) Use The FOIL method: (a + b) (c + d) = ac + ad + bc + bd.
