Answer:

c = 55° and d = 125°

Explanation:

Given that,

\angle a=85^{\circ}\\\\\angle b = 40^{\circ}

We need to find the measure of angle c and angle d.

We know that the sum of angles of a triangle is 180 degrees. So,

a+b+c = 180

85+40+c = 180

125+c=180

c = 180-125

= 55°

Using exterior angle theorem,

d = a+b

d = 85+40

d = 125°

Hence, c = 55° and d = 125°

Tides that occur during the first and third quarters of the moon

Featured snippet from the web
During a full or new moon, when the Earth, moon and sun align, spring tides form, creating higher and lower than normal tides. During the first- and third-quarter moon phases, when the moon and sun are at right angles to the Earth, neap tides occur, creating low and high tides with minimal difference in heights.
