Answer:
10°
Step-by-step explanation:
180-20 = 160
<BCA = 160°
AC=CB because its Radius
so the angle for <CBA and <BAD also the same
(180 - 160) ÷ 2 = <BAD
<BAD = 10°
Answer:
remember its a right angle so 90
Step-by-step explanation:
Answer:
because the light from the sun reflects off of the ocean and because of this it turns out sky blue.
Step-by-step explanation:
most of the earth is made up of water and the reason why you can get sunburned real bad when you swim is because light reflects off of the water.
hope this helped!
p.s it would be cool if you gave me brainliest.
Answer:
The diagonal must be 17 ft
Step-by-step explanation:
To determine the diagonal, we will use the Pythagorean theorem. That is for right triangles (which means the angle is 90 degrees)
a^2 + b^2 =c^2
where a and b are the legs and c is the hypotenuse
a = 8 ft and b = 15 ft because these are the sides of the wall and the hypotenuse will be the diagonal
8^2 + 15^2 = c^2
64+225 = c^2
289 = c^2
Take the square root of each side
sqrt(289) = sqrt(c^2)
17 =c
The diagonal must be 17 ft
