∠ 1 = 66°, ∠ 2 = 114°

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles and are supplementary ( sum to 180° ), then

2x + x + 81 = 180 , that is

3x + 81 = 180 ( subtract 81 from both sides )

3x = 99 ( divide both sides by 3 )

x = 33

Thus

∠ 1 = 2x = 2 × 33 = 66°

∠ 2 = x + 81 = 33 + 81 = 114°

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
