Answer:
146°
Step-by-step explanation:
You're given an angle, where the vertex is the center of a circle. This makes the angle's rays <em><u>two radii</u></em> of the circle. You are then given the length of 1/360th of the circle, which is .51cm, which is also 1 degree of the circle.
If the arc of the circle between the angle's rays is 74.46 cm. It becomes a division problem:
After the division, the fraction simplifies to 146, which is 146 segments of .51cm in the arc, and since .51cm is equivalent to 1 degree of the circle, the arc is 146 degrees.
Answer:
=(x-3)(x+7)
Step-by-step explanation:
To factor the trimonial: , we follow these steps:
Step 1: Multiply the first and last term
Step 2: List out product factors of the term derived above
Step 3: Determine which of the factors sum up to the middle term 4x
The required product is: -3 and 7
Therefore: -3x+7x=4x
Step 4: Replace the middle term by the expression derived in step 3 and factorize.
