Answer:
point-slope form: y - 1 = -4/5(x - 8)
slope-intercept form: y = -4/5x + 7.4
Step-by-step explanation:
Find slope using the points (8, 1) and (-2, 9):
m = (y₂ - y₁) / (x₂ - x₁)
= (9 - 1) / (-2 - 8)
= 8 / -10
m = -4/5
Find y-intercept using slope m from above and anyone of the given points, let's use (8, 1):
y = mx + b
1 = -4/5(8) + b
1 = -6.4 + b
b = 7.4
Use slope m and y-intercept b above to form equation of line in slope-intercept form:
y = mx + b
y = -4/5x + 7.4
For point slope form use slope m from above and a point, again let's use (8, 1):
y - y₁ = m(x - x₁)
y - 1 = -4/5(x - 8)
Answer:
x = 45°
Step-by-step explanation:
From the triangle given in the picture,
It's given that two sides of the triangle are equal so the triangle is an isosceles triangle.
By the property of isosceles triangle,
Opposite angles of the equal sides are equal in measure.
By triangle sum theorem,
x + x + 90° = 180°
2x + 90 = 180
2x = 180 - 90
x =
x = 45°
