Answer:

m∠7=34°

Step-by-step explanation:

m∠2=m∠8=146° because alternate interior angles are congruent.

m∠7=180-m∠8=34° because it is a linear pair.

Answer:

∠7 = 34°

Step-by-step explanation:

Since r and s are parallel lines, then

∠2 and ∠5 are same- side interior angles and are supplementary, thus

∠5 = 180° - ∠2 = 180° - 146° = 34°

∠7 = ∠5 = 34° ( vertical angles are congruent )

Find the area of the circle
motikmotik
The formula is \pi r², and to find r, or radius, you divide the diameter by 2. Your radius is 12.5, so you just plug that into your formula, and you have pi(12.5)², and simplify that to pi(156.25) and then your answer is <span>490.873852123. You probably want to round to the nearest hundredth, I don't know if you have specific directions, but if so your final answer would be 490.87.</span>
