Exterior angle c = the sun of the two opposite interior angles a and b.
10x -23 = 5x -17 + 7x -26
Combine the right side:
10x -23 = 12x -43
Add 43 to both sides:
10x +20 = 12x
Subtract 10x from both sides:
20 = 2x
Divide both sides by 2
X = 10
Now you have x replace it in the equation for A:
A = 5x -27 = 5(10) -27 = 50-27 = 23
Angle A = 23 degrees.
Imma start that lesson in about two years so sorry I can’t answer this question I
For this case, we convert the mixed numbers into fractions:
Now, rewriting the expression in three equivalent forms we have:
Answer:
Answer:
A)
Step-by-step explanation:
-6a + 2(2a + 2) = -6a + 4a + 4
= -2a + 4
Pretty sure it would be 21x^2+16x+17y
