Answer:
A = 22 degrees
Step-by-step explanation:
ABC is a right angle triangle, and angle ACB=68 degrees
hence, the angle BAC or angle A = 90-68 = 22 degrees

có hai phát biểu là mệnh đề, đó là câu 2 và câu 4
Step-by-step explanation:
13.89%
The value of the first die can be any number except for 1 because even if the second die rolls a 6, the total will only be 7. This means that there is a 5/6 chance of rolling an appropriate number with the first die. The second die has a 1/6 chance of rolling any given number. Any given number can be added to only one of the five numbers from the previous die to equal an 8. As a result, both numbers must be multiplied.
5/6 x 1/6 = 5/36 or 13.89%
First of all, look at the figure, The ABC orientation is changed from clockwise to counterclockwise, so an odd number of reflections are involved.
Second, look at the answer choices. Right away, you notice that the last choice (E) involves two reflections. That cannot be the transformation you see. Since that is what the question is asking for, the appropriate choice for the transformation NOT done is ...
... E. reflection across the x-axis followed by a reflection across the y-axis
_____
I have to admit, I went through each of the choices to see if it would work to produce the image you see. All choices except E will do that. All that work turned out to be unnecessary.
