Answer: B. 30
<u>Step-by-step explanation:</u>
When given a secant and a tangent, the formula is:
exterior of secant × secant = tangent²
KM × JK = LK²
10 × (JM + 10) = 20²
10JM + 100 = 400
10JM = 300
JM = 30

Answer:
C. 1 2/3
Step-by-step explanation:
5 - 3 1/3
We can also convert 5 into a fraction with the same denominator like this:
Since we’re trying to make 5 a fraction with a denominator of 3, leave 4 as the whole number and 3/3 as the fraction
4 3/3
4 3/3 = 5 because 3/3 = 1 and 4 + 1 = 5
Now we can subtract!
4 3/3 - 3 1/3 = 1 2/3
Step 1. Subtract the whole numbers
Step 2. Subtract the numerator
Step 3. Leave the answer with the same denominator
To get t on one side, we have to use inverse operations to get rid of the 5.
1. Use inverse operation of multiplication to get rid of 5. Which would be division.
2. Divide both sides by 5.
5t/5 = 7 1/2 / 5
3. Solve.
5t/5 = t and 7 1/2 /5 = 1 1/2
7.5 / 5 = 1.5
Therefore, your answer would be C. divide both sides by 5, and the answer is 1 1/2.
