Answer:
<h3>
126°</h3>
Step-by-step explanation:
given <abd = 48 and <dbc = 78, hence the addition rule is true<abc = <abd + < dbc

You count each unit square and it counts as one so for number two from point o to point a there are 5 unitsif each side we’re 5 hints and there are 6 sides you multiply five by six to get the answer of 39 for number three
Step-by-step explanation:
y = -2x² + 4x + 1
Complete the square.
y = -2 (x² − 2x) + 1
y = -2 (x² − 2x + 1) + 1 − (-2)(1)
y = -2 (x − 1)² + 3
The vertex is (1, 3). The leading coefficient is negative, so the vertex is a maximum.
