Answer: -80
Step-by-step explanation:
Answer:
option B. 
Step-by-step explanation:
we know that
1) The two diagonals of a rhombus are perpendicular
2) The sum of the interior angles in any triangle must be equal to 180 degrees
Let
O ----> the intersection point of the diagonals of the rhombus
In the right triangle OAD

solve for x




180 + 30x = 60 + 50x
⇒ 20x = 120
⇒ x = 6 minutes

Answer:
1 ≤ x < 7
Step-by-step explanation:
−2+3≤x−3+3<4+3 (Add 3 to all parts)
In math, the word unknown is also called to the missing term of a number sentence. This missing term is a missing piece that has to be solved.
Let us have A x 60 = 120, since A has no numerical value, it is considered as the missing term. How can we get the value of the missing term? first, study the number sentence. Find out the rule, then apply it.
The value of A on the equation above is 2. Here's how:
A x 60 = 120
A=120÷60
A=2
The value A is 2, therefore the missing term is 2.
