t = 
multiply both sides by 6rt
6crt = 1 ( divide both sides by 6ct to obtain r )
t =
The answer to the question is-20
|-20|= 20
Answer:
mZWX = 214°
Step-by-step explanation:
In a circle C, XR and WZ are two diameters.
∠ XCW = 34° and ∠ YCZ = 86°
We have to find the measure of arc ZWX
Since ∠XCW + ∠XCY + ∠YCZ = 180° [ angles on a straight line ]
34° + ∠XCY + 86° = 180°
120° + ∠XCY = 180°
∠XCY = 180 - 120 = 60°
Now arc ZWX = 360° - (∠XCY + ∠ YCZ)
= 360° - (60° + 86°)
= 360° - 146°
= 214°
Therefore answer is arc ZWX = 214°
Answer: x= 63, y= 27
Step-by-step explanation:
x and angle measure 117 are a linear pair. They sum to 180.
117+x= 180. Subtract 117 from both sides.
x = 63
Looking at the relationship of x and y, the diagram shows that the two together equal 90 degrees. Add the two together and set equal to 90.
63+y= 90. Subtract 63 from both sides.
y = 27
Answer:
7
Step-by-step explanation:
x * x = 7x
7 x 7 = 7 x 7
49 = 49
so if x is 7, the equation is true...
