B. use the sine and cosine values of special angles to find the sum: sin30+cos60.

sin30+cos60 = 1.

Step-by-step explanation:

Use the right angles triangle with angles 90-8=60-30.

The hypotenuse = 2 and the 2 legs have values of 1 and √3.

The 30 degree angle is opposite the leg of measure 1.

sin 30 = opposite / hypotenuse 1/2 and cos 60 = adjacent / hypotenuse  1/2 so the sum is 1.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
