Answer: 17.9
Step-by-step explanation:
Using Heron's formula:
Area of a triangle is given by:
√s(s-a)(s-b)(s-c)
Where a, b and c ara sides of the triangle and
S = (a+b+c) / 2
In the question above sides are :
XY=XZ= 20 and YZ=18
S = (20 + 20 + 18) / 2 = 58/2 = 29
Area = √29(29-20)(29-20)(29-18)
Area = √29(9)(9)(11)
Area = √25839
Area = 160.74513
Altitude = height(h)
Area = 0.5 × base × height
Base = yz = 18
160.74513 = 0.5 × 18 × h
160.74513 = 9 × h
h = 160.74513 / 9
h = 17.9 (3 s.f)

two angles are coterminal, namely land on the same spot on the circle.
let's check.
let's firstly divide 1965° by 360°, since 360° is a full circle, that way we know <u>how many full circles are</u> in 1965°.
1965 ÷ 360, gives us a quotient of 5 with some remainder.
5 * 360 = 1800, 5 full circles
if we subtract the full circles from 1965
1965 - 1800 = 165
low and behold, the remainder from that division is 165° ✔
in other words, 1965°, goes around the circle 5 times and then lands 165° after all that, in the same spot as 165°.
