In the diagram below, you are given that ∠AVD = ∠BVE = ∠CVF= 90° and ∠CVD = 22°. If ∠AVB= ∠EVF, how many degrees are in the meas
lana66690 [7]

Answer:

m∠AVF = 158°

Step-by-step explanation:

In the diagram attached,

m∠AVD = m∠BVE = m∠CVF = 90°

m∠CVD = 22°

∠AVB = ∠EVF

Since ∠AVD = ∠AVC + ∠CVD

Therefore, 90° = m∠AVC + 22°

m∠AVC = 90° - 22°

             = 68°

Similarly, m∠CVF = m∠CVD + m∠DVF

90° = 22° + m∠DVF

m∠DVF = 68°

m∠AVC = m∠DVF = 68°

Now ∠AVF = ∠AVD + ∠DVF

                  = 90° + 68°

                  = 158°

Maria normally walks 3/4 of an hour each day.Today she walked 5/2 times as long as normal. Did maria walk for more than 5/2 hour
tankabanditka [31]

Answer:

Marie did not walk  \dfrac{5}{2} hours more, but she walk \dfrac{9}{8} hours more .

Step-by-step explanation:

Given as :

The normal hours did Maria walks each day = \dfrac{3}{4} hours

The hours did Maris walk today = \dfrac{5}{2} times normal hours walk

Or, The hours did Maris walk today = \dfrac{5}{2} ×  \dfrac{3}{4} hours

Or, The hours did Maris walk today = \dfrac{5\times 3}{2\times 4} hours

Or, The hours did Maris walk today =  \dfrac{15}{8} hours

Now, Let The difference between normal hours walk and today hours walk = x hours

So, x = \dfrac{15}{8} hours -  \dfrac{3}{4} hours

<u>Taking LCM</u>

Or, x = \dfrac{15 - 6}{8} hours

Or, x =  \dfrac{9}{8} hours

So, Maria walk \dfrac{9}{8} hours more

Hence, Marie did not walk  \dfrac{5}{2} hours more, but she walk \dfrac{9}{8} hours more . Answer
