Colors are Qualitative and Nominal: Qualitative, because there is no number involved for "color" and Nominal, because their is no natural ordering for color
Answer: (D) 9
<u>Step-by-step explanation:</u>
This is an isosceles triangle. Since the legs are congruent, then the base angles are congruent.
9x + 3 = 84
<u> - 3 </u> <u> -3 </u>
9x = 81
<u>÷9 </u> <u>÷9 </u>
x = 9
Answer:
We must have two angles and a side.
A is the correct option.
Step-by-step explanation:
For any triangle ABC, the law of sine is given by

From this formula it is clear that in order to find the length of the side of the triangle, we must have two angles and a side.
Let us understand this by assuming that we need to find a (length of the side). From the formula, we have

Thus, to find the length a, we must have b, sin A and sin B.
Hence, o find the length of the side of the triangle, we must have two angles and a side.
