7 0

Answer:

x = 67.5 \degree

Step-by-step explanation:

x + 3x + 90 \degree = 360 \degree \\  \\  \implies \: 4x = 360 \degree - 90 \degree \\  \\  \implies \: 4x = 270 \degree\\  \\  \implies \: x =  \frac{270 \degree}{4} \\  \\  \implies \: x = 67.5 \degree

ASAP, Can someone find the volume of this please?
kirill [66]

Answer:

416.52 cm cubed

Step-by-step explanation:

first find the volume of the rectangle using LxWxH and you get 360

then get the diamiter of the semi sphere by seing that it is the same size as the width. then to get the radius divide the diamiter by 2. the find the volume of the semi sphere using 2π3^r/3 and you get about 56.52 ( i say about because i used 3.14 instead of all of pie.) then add 360 and 56.52 and you get the volume of this which is 416.52 cm cubed. dont forget the cubed!

could i get brainliest? :)

2z + 4 ≤ - 2 ( subtract 4 from both sides )

2z ≤ - 6 ( divide both sides by 2 )

z ≤ - 3
