By sine rule,
sin40/45= sin<B/60
Angle B= 59.0
Remaining angles are 59.0 and 81.0
Step-by-step explanation:
1. Right angled triangle , scalene triangle
2. isosceles triangle, obtuse angled triangle
3. equilateral triangle
4. right angled triangle, isosceles triangle
5. scalene triangle, obtuse angled triangle
6. scalene triangle, acute angled triangle
Answer:
x= -14
Step-by-step explanation:
-x+8+3x=x-6
The first step is to simplify both sides
8+2x=x-6
Now you want to put all the xs on one side and the other like terms on the other side (Subtract both sides by x and subtract both sides by 8 so the x is alone on one side)
x= -14
X - 2y = - 9
7x + 2y = 1
x - 2y = - 9
(+)
7x + 2y = 1
___________
8x = - 8
x = - 1
- 1 - 2y = - 9
2y = 8
y = 4
