Sum of two interiors =Exterior

Angle beside x
180-(30+14)180-44136Measure of x
180-13644°Answer:
x = 44°
Step-by-step explanation:
According to the Exterior Angle Theorem of a triangle, the external angle is equal to the sum of the two interior opposite angles of a triangle.
This is because the interior angles of a triangle sum to 180° and angles on a straight line sum to 180°.
⇒ x = ∠CAB + ∠BCA
⇒ x = 14° + 30°
⇒ x = 44°
Proof
Interior angles of a triangle sum to 180°
⇒ ∠CAB + ∠ABC + ∠BCA = 180°
⇒ 14° + ∠ABC + 30° = 180°
⇒ ∠ABC = 180° - 14° - 30°
⇒ ∠ABC = 136°
Angles on a straight line sum to 180°
⇒ ∠ABC + x = 180°
⇒ 136° + x = 180°
⇒ x = 180° - 136°
⇒ x = 44°

Answer:
54 sq ft
Step-by-step explanation:
6ft x 3 ft = 18 sq ft
9 ft x 4 ft = 36 sq ft
18 sq ft + 36 sq ft = 54 sq ft
The choices should be in sq ft, not in sq cm
The value of area in sq cm would be far greater than the value of area in sq ft.

What is trigonometry?
Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms.
When a altitude is drawn from the base of the triangle
we can write
sinA=height/ a where a, is the side length of AB
also,cos C=height/a where a, is the side length of AB
Therefore,The pair of equations is where a, is the side length of AB

Step-by-step explanation:
1/10 = 0.1
399.2/0.1 = 3,992
Answer:
3990
Step-by-step explanation:
Place the decimal to a fraction:
399.2 = 399 2/10
Simplify = 399 1/5
Put in improper fraction = 1995/5
Simplify more = 399/1 or 399

If 25% of a number is 65 and 60% of the same number is 156, find 35% of that number.
Answers
Answer:
35% of that number is 91.
Step-by-step explanation:
we need to first find 25% of what number equals 65.
65×100÷25 = 260
Then, if you use the same method again, 60% of 260 would be 156.
We know "that" number is 260, and all we need to do is find 35% of it.
35% of 260 = 91

if f(x) = x^2 which equation represents function g?
Step-by-step explanation:
maby ( C) am not sure
The equation represents the function is g(x) = 3f(x).
What is Function?A function is an expression, rule, or law in mathematics that describes a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are common in mathematics and are required for the formulation of physical relationships in the sciences.
We have,
Function, f(x) = x²
The function g(x) is compressed horizontally by a factor of 3, to get the function g(x)
g(x) = kf(x)
Where k = 3.
So, we have:
g(x) = 3f(x)

B. x= 3,y= 6 squared root of 3

D. 2 squared root of 3, y= 6

Answer:
Option A
Step-by-step explanation:
To find all missing sides of a right triangle we use the sine, cosine or tangent ratio as below,
sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
Now we take an angle measuring 60°
sin(60°) = [tex]\frac{6}{y}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{6}{y}[/tex]
y = 4√3
tan(60°) = [tex]\frac{6}{x}[/tex]
√3 = [tex]\frac{6}{x}[/tex]
x = 2√3
Therefore, Option A will be the correct option.
