Answer:
x = 83°
Step-by-step explanation:
41, 56 and the missing angle = 180° ( form a straight angle )
missing angle = 180° - (41 + 56)° = 180° - 97° = 83°
The angle x and the missing angle are vertically opposite and congruent
Hence x = 83°

Answer:
The height of the triangle is 6.5cm
Step-by-step explanation:
First of all we need to use the formula to calculate the area of a triangle:
a = area = 45.5 cm²
b = base = 14 cm
h = height
a = (b * h) / 2
we replace with the known values
45.5cm² = (14cm * h) / 2
45.5cm² * 2 = 14cm * h
91cm² / 14cm = h
6.5cm = h
The height of the triangle is 6.5cm
Using your approximate y-intercept on the line of best fit, your equation would be y=11/7x + 3.
We find the slope by choosing two points that are on the line:
(9, 18) is easy to spot; and (2, 7) is fairly easy to spot as well. The formula for slope is:
m=y₂-y₁/x₂-x₁
m=7-18/2-9 = -11/-7 = 11/7
Slope intercept form, y=mx+b, has the slope and the y-intercept. Plugging those in we have y=11/7x+3.
