Answer:
x=21
Step-by-step explanation:
We know that C is a right angle, which means that x + 3x+6 = 90

Have a nice day. hope I helped please rate brainliest!
Answer:
SA = π3^2 + π3(7.5)
Step-by-step explanation: r is radius and L
is r*l/2
so 3*5/2=15/2=7.5
seriously look at a problem more carefully and memorise your formulas!
Answer:
Step-by-step explanation:
The difference of the rational and and irrational number is always an irrational number.
Correct choice is B
The area is 28.26
to find the radius you have to divide the diameter by 2 which you’ll get 3
then plug it into the equation
A=3.14•3^2
Angle 2 is 180-127=53 degrees
angle G is 90
triangle has a total of 180 degrees, so angle 1 is 180-90-53=37 degrees
