The measures of Z1 and 22 are 30% and 45% of the sum of the angle measures of the triangle. Find the value of x.

45 degree or 25%

Step-by-step explanation:

sum of angles of triangle= 180 so

-----> angle 1

(note: 30% is equal to )

------> angle 2

lets add angle 1 and 2 together

54+81=135

now lets subtract it from 180 to get the remained angle

180-135=45 and if you want it in % so you just get 100%-(30%+45%)= 25%

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
