Answer:
b
Step-by-step explanation:
the hypotenuse is equal to the square root of 2 times x in a 45 45 90 right triangle
the square root of 2 times the square root of 2 cancels out to equal 2 and 2 times 3 is 6 so the hypotenuse equals 6
3x+8=5x-1
3x-5x=-1-8
-2x=-9
x=4,5
AM=3x4,5+8=21,5
MB=5x4,5-1=21,5
AB=AM+MB
AB=21,5+21,5=43
Hi
QPR = 74 (vertically opposite angles)according to angle sum property which means if we add all the angles of triangle we get 180 degrees
So,
PQR=180-(74+51)
180-125=55
So answer is 55 degrees
In the third equation, the left side has ab.
You are solving for a, so you need a alone.
Dividing ab by b gives you a alone.
Answer: The third choice.
