is a diameter of D, and m BDC = 70°. What is the measure of ADB? 70° 30° 110° 90° Next Question

The measure of ADB is 110°.

Solution:

m(ar BDC) = 70°

The measure of the central angle is congruent to the measure of the intercepted arc.

⇒ m∠BDC = m(ar BDC)

⇒ m∠BDC = 70°

Sum of the adjacent angles in a straight line = 180°

⇒ m∠ADB + m∠BDC = 180°

⇒ m∠ADB + 70° = 180°

Subtract 70° from both sides.

⇒ m∠ADB = 110°

m(ar ADB) = m∠ADB)

m(ar ADB) = 110°

Hence the measure of ADB is 110°.

i am thinking c. sorry if im wrong .

step-by-step explanation:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
