Answer:
Step-by-step explanation:
Sum of the interior angles of any triangle is 180°
<u>Let the third angle measure is x. Then the sum of angles is:</u>
- x + 11° + 52° = 180
- x + 63° = 180°
- x = 180° - 63°
- x = 117°
The point-slope form:

We have the point (-1, -4) and the slope m = -3. Substitute:

12,568,983
10,000,000+2,000,000+500,000+60,000+
8,000+900+80+3
Twelve million five hundred sixty-eight thousand nine hundred eighty-three
99,999,999
90,000,000+9,000,000+900,000+90,000+9,000+900+90+9
Ninety-nine million nine hundred ninety-nine thousand nine hundred ninety-nine
12,345,678
10,000,000+2,000,000+300,000+40,000+
5,000+600+70+8
Twelve million three hundred forty-five thousand six hundred seventy-eight
49,275,546
40,000,000+9,000,000+200,000+70,000+5,000+500+40+6
Forty-nine million two hundred seventy-five thousand five hundred forty-six
64,834,174
60,000,000+4,000,000+800,000+30,000+4,000+100+70+4
Sixty-four million eight hundred thirty-four thousand one hundred seventy-four
The answer is x= -2 i hope this helps!!!!
