Answer:
50°
I hope it will be useful.
Step-by-step explanation:
Since the triangle is isosceles(see the sides),
opposite angles to the equal sides are equal.
(Property of isosceles triangles)
v.i.z., 2x=100°
Answer:
B) UY
Step-by-step explanation:
From the given figure, TUYX is one of the side of the rectangular prism and UVYZ is another side of the rectangular prism.
The both sides are intersecting perpendicular in one edge, that is the line segment UY.
You can see it on the figure.
Therefore, the intersecting line is UY.
Answer:
The correct answer to given question is option (a).
Step-by-step explanation:
Given function: f(x)= -2|x+1|
we need to put random values of x in given function to see that range of the given function f(x) is all real numbers.
when:
x=0; f(0)= -2|0+1|= -2|1|= -2
when x is positive i.e. x>0
x=1; f(1)= -2|1+1|= -2|2|= -4
x=2; f(2)= -2|2+2|= -2|4|= -8
when x is negative i.e. x<0
x= -1; f(-1)= -2|-1+1|= -2|0| =0
x=-2; f(-2)= -2|-2+1|= -2|-1|=2 (with the help of mod property |-1|=1)
hence, we saw that
when we take x>0; f(x)<0
when x<0; f(x)>0
we can conclude from above steps that the range of function f(x)= -2|x+1| is all real numbers.
Step-by-step explanation:
- 4x+5= 20
- 4x=20-5
- 4x= 15
- x= 15/4
therefore the answer is option
b) X= 15/4
