RS and RT are tangents to the circle center o. Angle SRT=40 degrees. What is the size of angle SUT

is c (70 degrees) I hope it helps anyone.

Step-by-step explanation:

RS is a tangent ⇒ ∠OSR = 90°

RT is a tangent ⇒ ∠OTR = 90°

OSRT is a quadrilateral, so has an angle sum of 360°

⇒ ∠OSR + ∠SRT + ∠OTR + ∠SOT = 360°

⇒ 90° + 40° + 90° + ∠SOT = 360°

⇒ 220° + ∠SOT = 360°

⇒ ∠SOT = 140°

Now use the Angle at the Center Theorem

∠SUT = ½ × ∠SOT = ½ × 140° = 70°

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
