The vlaue of z is 27°
Step-by-step explanation:
Given,
The angle is 63°
To find the value of z
We know that the diagonals of rhombus perpendicularly bisect each other.
Again,
z+63°+90° = 180° [ sum of all the triangle is 180°]
or, z = 27°
Greetings.
The range is the set of y-value.
The range starts from the minimum point to maximum point.
Our minimum point starts at 0 and maximum point starts less than infinity.
Therefore the range is 0<=y<+inf
However, we do not often write that, although it is right.
Therefore we write as y≥0
Thus, the answer is B choice.
Answer:
I BELIEVE ITS C
Step-by-step explanation:
The quadratic formula is -b plus minus the square root of b^2-4ac all over 2a.
Here, a=1, b=13, and c=30.
The only option that fills in the values correctly is D
