For triangles, all angles total 180°
For quadrilaterals, all angles total 360°
Parallelograms have equal opposite angles, so each adjacent pair is 180°
Hexagons are 720°
3. 180 - (90 + 30) = 180 - 120 = 60°
4. 180 - (45 + 45) = 180 - 90 = 90°
5. 360 - (135 + 70 + 93) = 360 - 298 = 62°
6. 180 - 60 = 120°
7. 180 - (120 + 37) = 180 - 157 = 23°
8. Perfect hexagon: 120°
9. Parallelogram: 70°
10. 360 - (90 + 90 + 67) = 360 - 247 = 113°
Answer:
X = (18, 0 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( , )
let the coordinates of X be (x, y ) then equate to the coordinates of midpoint
= 8 ( multiply both sides by 2 )
x - 2 = 16 ( add 2 to both sides )
x = 18
and
= - 2 ( multiply both sides by 2 )
y - 4 = - 4 ( add 4 to both sides )
y = 0
coordinates of X = (18, 0 )
What do you mean? Pls state the question correctly
without the sales tax he wil pay
175 - 175 x 45%
so he will pay 175 x 55% = $ 96,25
then we add the tax of 12%
96,25 + 96,25 x 12%
so = 96,25 x 1,12 = $107,80
She would need 131 feet
(8x12)+(5x7)
