Step-by-step explanation:
The statements are
1.Draw Oa,Ob
2.OR is perpendicular to AB
3.OR is congruent to OR
4.OA is congruent to OB
5.Triangle AOR is congruent to BOR.
6.AR is congruent to AB.
The reasons are
1.Auxalaritly lines
2 Radius are perpendicular to tangent
3.Reflexitive
4.Radii of same circle are equal
5.HL theorem, (since we know hypotenuse and a leg)
6.CPCTC
Yes, that is a correct statement.
But im left wondering what is the darn question
Solution:
As given ∠AXC is a straight angle and ∠AXD measures 90°.
Measure of a straight angle =180°
∠AXD = 90°
∠AXD+∠DXC=180°[ ∴∠AXC is a straight angle]
→90° +∠DXC=180°
→∠DXC=180°-90°
→ ∠DXC=90°
∠DXC measures right angle i.e having measure 90°.
I am going to assume you meant 4 and one half hours. So you want to divide the distance by time. So 288 divided by 4.5 hours is 64. So Miley's average speed is 64 miles per hour.
P = 2w + 2L
Flip
2w + 2L = P
Subtract both sides by 2L
2w = P - 2L
Divide both sides by 2
w = (P - 2L) / 2
You chose the right answer choice!
Have an awesome day! :)
