Answer:
Step-by-step explanation:
Given figure is of a rhombus.
Measures of the opposite angles of a rhombus are equal.
Therefore,

Answer:
x = 9
(5x9) - 1° = 45 - 1 or 44°
Step-by-step explanation:
the little square indicates the angle is a right angle, measuring 90°
therefore, you can solve for 'x' by creating this equation:
46 + 5x-1 = 90
45 + 5x = 90
5x = 45
x = 9
Answer:
You make one number positive.
Step-by-step explanation:
A negative number multiplied by a negative number is positive, so that means that if you choose two of the numbers in this expression you will get a positive number. However, there is still one negative number left and you will get a negative product if you multiply, because a positive number multiplied by a negative number is a negative number. If you make this last number positive you will get a positive product.
