Answer:2/6
Step-by-step explanation:
To find m<3, we can use the angle sum of triangles, in which the addition all angles in a triangle must be equal to 180°.
In this case:
m<3 +52°+29° = 180°
m<3 + 81° = 180°
m<3 = 180°-81°
m<3 = 99°
To find m<4, we can use adjacent angles on a straight line, where the addition of angles on a straight line must be 180°.
In this case:
m<4 + 99° = 180°
m<4 = 180°-99°
m<4 = 81°
Therefore m<3 is 99° while m<4 is 81°.
Hope it helps!
When x=-2, y=4x = 4(-2) = -8 .
So all the items are half price. Then what is the half of 3?
3/2 = 1.5 because 1.5 + 1.5 = 3.
So the jacket was sold for $1.5.
P.S.: Why is the jacket so cheap?
Answer:
310.8m²
Step-by-step explanation:
<u>GIVEN :-</u>
- Diameter = 9m ⇒ Radius (r) = 9/2 = 4.5m
- Slant height (l) = 13m
<u>TO FIND :-</u>
- Surface area of the whole figure.
<u>FORMULAES TO KNOW BEFORE SOLVING :-</u>
- Curved surface area of cone =
(where r = radius & l = slant height) - Curved surface area of hemisphere =
(where r = radius)
<u>PROCEDURE :-</u>
In the figure , the cone is mounted on a hemisphere.
⇒ Radius of cone = Radius of hemisphere = 4.5m
Total surface area of the figure = Curved surface area of both cone & hemisphere.
⇒
- Curved surface area of cone =
≈ 183.7m²
- Curved surface area of hemisphere =
≈ 127.1m²
∴ Total surface area = 183.7 + 127.1 = 310.8m²
