Angle D and Angle E are vertical angles. If the measure of angle E is 105°, find the measure of angle D.

D = 105

Step-by-step explanation:

Vertical angles are equal

D = E

D = 105

D is 105°

Step-by-step explanation:

Vertical angles have the same measures.They are congruent to each other.So if D and E are vertical angles,  and E is 105 degrees then D will have the same measure.

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
