Answer:
Figures A,D are polygons.
Reason:
Polygon is a closed figure with atleast three strange lines and angles.
the inside of quadrilateral is always 360°.So add 75°,90° and 75° and then subyaract from360°.
x+75°+75°+90°=360
×+240°=360°
x=360°-240°
x=120°
Answer:
V=1/3hπr². Basically, 1/3 x height x 3.14 (pi) x radius squared.
Step-by-step explanation:
The formula of figure 2 would be 1/3 x 15 x 3.14 x 8 squared. The volume of figure 2 would be 1005.30965
the formula for figure 3 would be 1/3 x 15 x 3.14 x 4 squared. The volume of it would be 251.32741
hope this helps! (Also please make me brainliest if this helps u :) )
Answer:
X=7
Step-by-step explanation:
HJ + JK = HK
3(X + 2) +(3X - 4) = 44
3X + 6 + 3X - 4 = 44
6X + 2 = 44
6X = 42
X = 7
No: 6(-5) +5 = 5(-5) +8 + 2(-5)
-30 + 5 = =25 + 8 - 10
-25 ≠ -27
