Answer:
Step-by-step explanation:
take x degree as reference angle
using tan rule
tan x=opposite/adjacent
tan x=45/35
tan x=1.285
x=1.285
x=52.10 degree
x=52.1 degree
The triangle Inequality Theorem states that if the longest side is shorter than the sum of the other 2 sides, it will form a triangle.
7< 4 + 5 so it forms a triangle.
It is a scalene triangle (all 3 sides are not equal).
It makes an obtuse triangle. (To see why, click here: http://www.1728.org/triantest.htm )
Answer:
11.2 feets
Step-by-step explanation:
Angle, P = 180 - (38 + 90) = 52
Using trigonometry :
Length pq:
SinP = opposite / hypotenus
Sin52 = 8.8 / pq
0.7880107 * pq = 8.8
pq = 8.8 / 0.7880107
pq = 11.167361
Hence, length of pq = 11.2 feets
The x-intercepts of a function are the values of the functions when y = 0.
Given the table below
x f(x)
-4 0
-2 2
0 8
2 2
4 0
6 -2
As can be seen from the table, the y [f(x)] values are 0, when x = -4 and when x = 4.
Therefore, the x-intercepts of the continuous function are (-4, 0) and (4, 0).
Answer:
rearrange the formula A=lw and make the width the subject of the formula
therefore to find width, the formula is w=A/l
