CAN SOMEONE PLEASE HELP ME PLEASE

Answer:

∠CDF= 70°

Step-by-step explanation:

there's an easier way to do this which is adding the angles ∠EDG and ∠GDF and then subtracting that from 180° but, checking your work in the same process is a little more work.

First, I'd like to find ∠ADB.

  1. 85°+70°= 155°
  2. 180°-155°= 25°
  3. ∠ADB= 25°

Second, add all the angles together.

  1. 70°+50°+60°+85°+25°= 290°
  2. 360°-290°= 70°

a bird is flying to the right when a gust of wind causes the bird to accelerate leftward at 0.5m/s2 for 3s
natta225 [31]

Answer:

4 m/s

Step-by-step explanation:

A bird is flying to the right when a gust of wind causes the bird to accelerate leftward at 0.5 m/s^2 for 3 s. After the wind stops, the bird is flying to the right with a velocity of 2.5 m/s.

Assuming the acceleration from the wind is constant, what was the initial velocity of the bird before the gust of wind?

Let say Initial Velocity of Bird = U m/s

Final Velocity of Bird V = 2.5 m/s

acceleration a = -0.5 m/s²  ( as opposite to the fly direction)

Time T= 3 sec

Applying formula

V = U + aT

=> 2.5 = U + (-0.5)3

=> 2.5 = U -1.5

=> U = 4 m/s

the initial velocity of the bird before the gust of wind =  4 m/s

Lady bird [3.3K]

Answer:

(A) technology, reward systems, and infrastructure.

Explanation:

Misalignments can occur in technology, infrastructure, and reward systems, and also in marketing. A company is misaligned when people pursue goals and agendas that are incongruent with each other and do not combine to effectively advance a single purpose.

In fact, in marketing, misalignment is the scourge of the modern marketing department, and it’s no surprise why there is so many channels to manage with no way to predict the customer journey. Highly fragmented roles and teams executing on compressed time cycles. Intense pressure to drive business impact, while staff are drowning in disconnected data and unclear strategy.
