Answer:
Subtract ax from both sides. ax + by − ax = c − ax.
Simplify. by = c − ax.
Divide both sides by b ; b ≠ 0. by b = c b − ax b ; b ≠ 0.
Simplify. y = c − ax b ; b ≠ 0.
A right triangle has an angle that is 90 degrees.
An acute triangle has all three angles less than 90 degrees.
An obtuse triangle has one angle greater than 90 degrees.
Hope that helps.
Answer:
B
Step-by-step explanation:
Answer:
The second and fourth one is right
Step-by-step explanation:
A²+ B² = C²
15² + 20² = 25²
225 + 400 = 625
625 = 625
16² + 30² = 34²
256 + 900 = 1156
1156 = 1156
