The given Angles (4x + 2) and (3x + 3) are forming linear pair, so

  • 4x + 2 + 3x + 3 = 180

  • 7x + 5 = 180

  • 7x = 180 - 5

  • 7x = 175

  • x =  \dfrac{175}{7}

  • x = 25

now, let's find Angle DCB :

  • 3x + 3

  • (3 \times 25) + 3

  • 75 + 3

  • 78 \degree

A boat traveled 27 miles in 2 hours. At this, how many miles will the boat travel in 1/2 hour?
Fantom [35]
You do distance over time to get the rate, so you'd do 27/2= 13.5mph then divide that in half since you're asking for the distance traveled in half that hour so you do 13.5/2 and you get 6.75 miles traveled in half and hour.

In the figure, PA and PB are tangent to circle O and PD bisects ∠BPA . The figure is not drawn to scale. For m
Mademuasel [1]

Angle AOC = 46°   Find angle BPO

We have congruent right triangles PAO and PBO, right angles A and B.

So AOC=BOC=46 degrees,

PBO is a right angle so BPO is complementary to BOC, so 42 degrees

Answer: 42 degrees
