Could a triangle have angle measures of 112° 57° and 11°? explain hw u know

If you add all three interior angle measures together in a triangle it will always equal 180°.. To find a third angle you will subtract the sum of the two given angles from 180°. Look at the 3 examples below.

The additional of a triangle's degree measure will always equal 180˚

When the question asks you if a triangle with 112˚, 57˚, and 11˚, you have to add them up and make sure they equal to 180˚

In this case, 112˚ + 57˚ + 11˚ DO add up to 180˚, and is indeed a triangle.

oof tough question

step-by-step explanation:

sorry i can't ya : c gl tho

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
