Answers
Answer:
Since the triangle is a right angled triangle, one of the angles is 90°. In the right angled triangle, the acute angles are in the ratio 4:5. Let the measures of the acute angles of the triangle in degrees be 4k and 5k, where k is a constant.
Step-by-step explanation:
hope it helps.
Answer:
40and50
Step-by-step explanation:
let the acute angles be 4x and 5x then,
4x+5x+90=180 [sum of all angles of a right angled triangle]
or,9x=180-90
or,x=90/9
x=10

.2333 repeating as a fraction
Answers
Answer and Step-by-step explanation:
0.2333...
First, multiply the number by 10 (because there is 1 number being repeated.
2.333.....
Now subtract by the original number.
2.333...
- 0.2333...
2.10
Write this as an equation:
(10 x fraction) - fraction = 2.1 (10 x fraction) - fraction = 9 x fraction
9 x fraction = 2.1 (Divide both sides by 9)
[tex]\frac{2.1}{9}[/tex] = [tex]\frac{7}{30}[/tex]
[tex]\frac{7}{30}[/tex] is the answer.
(To check, do 7 divided by 30 in a calculator, and you will get 0.233 repeating)

Answers
Answer:
(x – 3)^2+ (y – 2)^2 = r^2
Step-by-step explanation:
The co-ordinates of the center=(3,2)
The formula for the equation of a circle is (x – h)^2+ (y – k)^2 = r^2,
(h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
Therefore, (x – h)^2+ (y – k)^2 = r^2
=(x – 3)^2+ (y – 2)^2 = r^2
You can find r^2the equation.

If f(x) = 4x + 3 and g(x) = 22 – 3, then f(g(4)) = ???
Answers
f(19) = 79
So f(g(4)) = 79
Answer:
f(g(4))=79
Step-by-step explanation:
given:
f(x) = 4x + 3
g(x) = 22 – 3
g(x) = 19
the x in parentheses represents x's value. if it is just x then example f(x)=3x would be 3x. if f(x) was f(2)=3x, then x would be 2 and f(2)=3x would be 3*2=6
f(g(4))
first solve g(4)
g(x) = 19
g(4)=19 because there are no x
then substitute
f(g(4))
f(19)
f(19) = 4x + 3
all x become 19
f(19) = 4(19) + 3
=76+3
=79
