Let x be one angle and x +28 be the second angle.
X + x+ 28=90
2x = 62
X=31, x+ 28=59
So 31 & 59 are the angles
Answer:
78
Step-by-step explanation:
Sorry if I’m wrong learned that a long time ago don’t really remember
The answer would be y=60.
I think.
Answer:
(x + 3)²
Step-by-step explanation:
Given
x² + 6x + 9
This is a perfect square of the form
(x + a)² = x² + 2ax + a²
Compare like terms
a² = 9 ⇒ a = 3 and 2a = 2 × 3 = 6, thus
x² + 6x + 9 = (x + 3)² → D
