Answer:
129° and 37°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
(a)
∠ 1 is an exterior angle, thus
∠ 1 = 62° + 67° = 129°
(b)
∠ 1 + 115° = 152° ( subtract 115° from both sides )
∠ 1 = 37°

Answer:
Equation of the line: ![3y=x+10](https://tex.z-dn.net/?f=3y%3Dx%2B10)
Step-by-step explanation:
If an equation of a line is perpendicular, its gradient will be such that: ![m_1 \times m_2 = -1](https://tex.z-dn.net/?f=m_1%20%5Ctimes%20m_2%20%3D%20-1)
Since the gradient /slope of the given equation can be inferred as -3, the gradient of the perpendicular line will be
.
Coordinates of a point on the line are (3,-1)
![(y-y_1) = m(x-x_1)\\\\(y-3) = \frac{1}{3} (x+1)\\\\3(y-3) = (x+1)\\3y -9= x+1\\3y = x+1+9\\3y = x+10](https://tex.z-dn.net/?f=%28y-y_1%29%20%3D%20m%28x-x_1%29%5C%5C%5C%5C%28y-3%29%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%28x%2B1%29%5C%5C%5C%5C3%28y-3%29%20%3D%20%28x%2B1%29%5C%5C3y%20-9%3D%20x%2B1%5C%5C3y%20%3D%20x%2B1%2B9%5C%5C3y%20%3D%20x%2B10)
