Step-by-step explanation:
Measure of the length of an arc of a circle is given as:

Answer:
slope = - 3 y-intercept = 36
Step-by-step explanation:
12x + 4y = 144 , will allow this to be done.
so 4y = - 12x + 144
now dividing both sides of the equation by 4 will give
y = - 3x + 36 , which is now in the required form
slope = - 3 and y-intercept = 36
Answer:
58.29 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A =
h (a + b) , substitute given values into formula
A =
× 6.7 × (7 + 10.4)
= 3.35 × 17.4
= 58.29 cm²

Answer:
I‘m pretty sure its a special right triangle, basically a 30, 60, 90 triangle. I checked with the formula and it’s correct. So the angle W is wither a 60 Degree or 30 degree and I‘m on the side of 30 degrees.
So I’m pretty sure its 30 degree.
The formuda is the hypotenuse is 2x and the (a) (3 in this case) is x. The 5 would come out as the formula 3
. Now we know the sides, 3, 5 and 6 so we just plug it in and solve for the square root and it equals to ABOUT 5.
I’m not sure if I’m correct but I’m not confident.
