Question

Here a easy one tooooooooooooo

Answer 1

Remember:
A triangle is always 180 degrees and so is a straight line so 360 degrees in total:

1) Add 92 and 123 which equals 215
Then 360 subtracted by 215 is 145

Answer: 145

2) add 100 and 25= 125
360-125= 235
Answer: 235 degrees

Answer 2

Answer: See explanation

Step-by-step explanation:

1.) There's an angle supplementary to m∠123°, that angle is y

y and m∠123° are supplementary since they're linear pairs

y + 123 = 180

Subtract both sides by 123

y = 57°

Now we know at least two angles of the triangle, x + y + m∠92° has to be 180° because they form a triangle.

x + y + m∠92° = 180°

x + 57 + 92 = 180

x + 149 = 180

Subtract both sides by 149

x = 31°

2.) We have to figure out the missing angle in the triangle, that missing angle is once again, y.

y + 100 + 25 = 180

y + 125 = 180

y = 55°

x and y are supplementary angles because they form a straight line

x + y = 180°

x + 55 = 180

Subtract both sides by 55

x = 125°
