Answer:
Step-by-step explanation:
The dashed vertical line indicates that -3 is not included so x is greater than -3. The diagonal line is solid indicating that it is included so y is greater than or equal to -4x/5 -2. So it is second answer.
Answer:
take 40 degree as reference angle
using sine rule
let opposite be x
sine 40=opposite/hypotenuse
0.64=x/7
0.64*7=x
4.48=x
Step-by-step explanation:
Answer : we can make only one angle with this because it is necessary to have AB as a base line because the given angle is of <B means we have to make angle at point B . if we take AC as a base line we can not draw angle because we have to make angle at point B so .
. draw a line of AB =7.6
.draw <ABC of 50 degree
.then from point A draw an arc of 5.4 cm at point c
join point A to point C
If a field is 900 meters squared and one side is twice as big as the other how big is each side
For this you can look at Sin Cos and Tan
A useful tip is S O/H C A/H T O/A
In this angle you have an opposite and an adjacent side to angle h.
So you’ll use Tan
You get
tan(x)= (2)/2root3
then you need to isolate the x value through the inverse of tan.
x= tan-1((2)/2root3)
x= 30
In a easier way you could’ve identified this as a 30,60,90 triangle from the side lengths.
