Step-by-step explanation:

so 180-50=130 so we have x and 130 now umm uuu o ok so the parellel lines it makes it to where there is gonna be 2 xs in the triangle so 180-130=50 50 divided by 2=25 so x = 25

BEG is a triangle. ABC and DEF are parallel lines. work out the size of angle x.
worty [1.4K]

Answer:

x=60^o

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the measure of angle BEG

we know that

m\angle BED+m\angle BEG+m\angle GEF=180^o ---->  by supplementary angles (form a linear pair)

substitute the given values

110^o+m\angle BEG+25^o=180^o

m\angle BEG=180^o-135^o=45^o

step 2

Find the measure of angle HBC

we know that

m\angle HBC+m\angle ABH=180^o ---> by supplementary angles (form a linear pair)

we know that

m\angle ABH=110^o ---> by corresponding angles

substitute

m\angle HBC+110^0=180^o

m\angle HBC=180^o-110^o=70^o

step 3

Find the measure of angle EBG

we know that

m\angle EBG+m\angle GBC+m\ angle HBC=180^o

substitute the given values

m\angle EBG+35^o+70^o=180^o

m\angle EBG=180^o-105^o=75^o

step 4

Find the measure of angle x

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle BEG

m\angle BEG+m\angle BGE+m\angle EBG=180^o

substitute the given values

45^o+x+75^o=180^o

x=180^o-120^o=60^o

zvonat [6]

Answer:

This cylinders volume, in terms of pi, is 144π m³

This cylinders volume, rounded to the hundredth place, is 452.39 m³

Step-by-step explanation:

volume of cylinder:

→ πr²h

→ π(4)²(9)

→ 144π

→ 452.39 m³ ......rounded to nearest hundredth
