Y=(-3) include parentheses
Explanation:
y=mx+b is the slope intercept form of a line where b and y is the intercept so,
x-y=x+3: y= -3
BD = AC Given. BD cuts AC in half. That's what bisectors do.
BD = BD Reflexive property of a line (it is always equal to itself).
<ADB = <ADC = 90o
DB is perpendicular to AC Given.
<ADB + <ADC = 180o The two are supplementary.
Each angle = 90o Perpendicular means that one line meets another at 90o
2x = 180
x = 90o
Since each of the enclosed angles = 90, two have two triangles congruent by SAS <<<< Answer
Answer:
AA similarly is correct....
The answer is 63.3
9.5 * 3 + 8.7 * 4 = 63.3
