check the picture below.
the line QS is just a flat-line and therefore it has 180° on either side, so the angle QPR is 57°, as you see there, and since we know the diameter is 20, that simply means the radius of the circle is 10.
Answer:
2
Step-by-step explanation:
Answer:
0.2 = 1/5
Step-by-step explanation:
Convert 0.2 into a fraction.
You get 2/10.
Now simplify that number by dividing both the numerator and the denominator by 2.
You get 1/5.
Since 1/5 = 1/5, 0.2 and 1/5 are equivalent.

Answer:
x = 30
ABC = 90
ACB = 30
Step-by-step explanation:
We know that if we add the 3 angles of a triangle together, it will come out to be 180 degrees, so..
60 + x + 3x = 180 subtract 60 from both sides and simplify
4x = 120 divide both sides by 4
x = 30
ABC = 3x
ABC = 3(30)
ABC = 90
