Answer:
18+12.125π units²
Step-by-step explanation:
The diameter of the semicircle can be found by the use Pythagoras theorem.
Δx²+Δy²=d²
Δx=3--1=4
Δy=3--6=9
d²=4²+9²
d=√(16+81)
Area=πr²/2
=π×(√(16+81)/2)²÷2
=[π×(97)/4]/2
=97π/8
=18+12.125π units²
97π/8 is equivalent to 18+12.125π units²
-2.5 is the slope and the equation is y=-2.5+9 hope this helps
Answer:
105°
Step-by-step explanation:
m(15) = 75°
Also it's given that m||n . So taking y as transversal ,
m(15) = m(13) = 75°
Also it's given that x||y . So taking m as transversal ,
m(13) = m(5) = 75°
Now m(5) & m(1) are linear pair. So ,
m(5) + m(1) = 180°
=> 75° + m(1) = 180°
=> m(1) = 180° - 75°
= 105°
Answer:
0.88
Step-by-step explanation:
-5.37 + 8.14 - 1.89
-5.37 + 6.25
= 0.88
