Answer:
The measures of each would be:
105° and 75°
Step-by-step explanation:
Supplementary angles are two angles whose measures sum up to 180° or they form a straight line.
So if an angle measures 30° less than the measure of its supplementary, it wold mean that both angles together is equal to 180°.
∠1 = x
∠2 = x-30°
∠1 + ∠2 = 180°
So here we plug in our equations:
∠1 + ∠2 = 180°
x + x - 30° = 180°
2x - 30° = 180°
We solve for the x then:
Add 30° on both sides of the equation:
2x - 30° + 30° = 180° + 30°
2x = 210°
Divide both sides by 2:
2x/2 = 210°/2
x = 105°
∠1 = 105°
Now we solve for the second angle:
∠1 + ∠2 = 180°
105° + ∠2 = 180°
Subtract 105° from both sides of the equation:
105° + ∠2 - 105° = 180° - 105°
∠2 = 75°
B. 4.5=2m+g
f. 9.25=3m+2g
1.25=m
sub
b. 4.5=2(1.25)+g
f. 9.25=3(1.25)+2g
b. 4.5=2.5+g
f. 9.25=3.75+2g
minus 2.5 from both sides on the b. equaion and minus 3.75 from both sides on the f. equation
b. 2=g
f. 5.5=2g
divide both sides of f. equation by 2
b. 2=g
f. 2.75=g
2.75-2=0.75

Answer: x=5 bc 5 times 5 is 25
Ste-by-step explanation:
Rewrite the equation in slope-intercept form
5x -2y = 28
Subtract 5x from both sides
-2y = -5x + 28
Divide both sides by -2
Y = 5/2x -14
The y intercept is -14
