Answer:
50°
Step-by-step explanation:
The missing angle, <C, is an angle on a straight line with the two other angles who measures are 65% each.
Therefore:
65 + 65 + C = 180° (angles on a straight line)
130 + C = 180
Subtract 130 from both sides
130 + C - 130 = 180 - 130
C = 50°

Answer:
The equation of the line is y = x + 1
Step-by-step explanation:
The equation of the line is y = m x + b, where
- m is the slope of the line
- b is the y-intercept
The rule of the slope of the line is m = , where
- (x1, y1) and (x2, y2) are two points on the line
∵ The line passes through points (3, 4) and (-4, -3)
∴ x1 = 3 and y1 = 4
∴ x2 = -4 and y = -3
→ Substitute them in the rule of the slope above to find it
∵ m = =
= 1
∴ m = 1
→ Substitute it in the form of the equation above
∴ y = 1(x) + b
∴ y = x + b
→ To find b substitute x by 3 and y by 4 in the equation
∵ 4 = 3 + b
→ Subtract 3 from both sides
∵ 4 - 3 = 3 - 3 + b
∴ 1 = b
→ Substitute it in the equation
∴ y = x + 1
∴ The equation of the line is y = x + 1

Answer: √58 or about 7.6
Step-by-step explanation:
use the distance formula: √((x1 - x2)² + (y1 - y2)²)
√((3 - 0)² + (7 - 0)²)
√((3)² + (7)²)
√(9 + 49)
√58
