Well, you take a set of numbers and you find the biggest number and you subtract the smallest number from it. that is the mean and the mean is the average number.
Answer:
<u>31°</u>
Step-by-step explanation:
As the opposing side and adjacent side of the angle x are given, we need to take the tan ratio of the angle.
=============================================================
Solving :
⇒ tan x° = 9/15
⇒ tan x° = 3/5
⇒ x = tan⁻¹ (0.6)
⇒ x = <u>31°</u>
Answer:
x = 50°
y = 50°
z = 80°
Step-by-step explanation:
working out x:
angles on a straight line add up to 180°
x + 130° = 180°
subtract 130 on both sides
x = 180° - 130°
x = 50°
working out y:
two vertical lines means that both sides are equal, so both angles are also equal (it's an isosceles triangle). This means that y is the same angle as x = 50°
y = 50°
working out z:
the sum of a triangle add up to 180°
add up the angles of x and y and equate to 180°
50 + 50 + z = 180
100 + z = 180
subtract 100 on both sides
z = 180 - 100
z = 80°

(4/7).(-3/5) = (4.(-3))/(7.5) = -12/35
(3/5).(-6/7).(-4) = (3.(-6).(-4))/(5.7) = 72/35
6/(1/8) = 6.8 = 48
