<span>A) 5x -9y = -17
B) 5x +3y = 19
If we multiply equation A by -1

<span>A) -5x +9y = 17 then add it to B)
</span><span>B) 5x +3y = 19
12y = 36
y = 3

Need helppppp I’m stuckkkk
Galina-37 [17]

Answer:

b) 94

Step-by-step explanation:

The Total Degree of a Triangle is 180 degrees. Knowing this, set up an equation.

68+26+x=180.

x is the complementary angle of the "?" angle.

Solve the equation.

94+x=180

x=86

Then Subtract 86 from 180 to find "?"

180-86=94

I hope this helps!

Step-by-step explanation:

Given:

Complementary angle = 68'

Angle measure = 90' - 68' = 22'

Supplementary angle = 180' - 22' = 158'

Angle classification = Acute angle

Given:

Supplementary angle = 161'

Angle measure = 180' - 161' = 19'

Complementary angle = 90' - 19' = 71'

Angle classification = Acute angle

Given:

Angle measure = 136'

Angle classification = Obtuse angle

Complementary angle = 136' - 90' = 46'

Supplementary angle = 180' - 136' = 44'
