Really hard geometry problems. Please help!

For #3 the answer is 48 degrees, #4 is 70 degrees

Step-by-step explanation:

3. CGA and BGD are verticle angles which means they are congruent, and (2x-10)+(x+4)+(x+10) is 180. Which gives you X=44, then you substitute x into x+4 which gives you 48.

4. CEB and BED are supplementary which means they make up 180. BED and CEA are verticle angles which means they are congruent. We know CEB is 110 which means BED is 70 because 180-110=70. BED and CEA are verticle angles which means CEA is also 70 degrees

i think #3 is 93 and #4 is 70

Step-by-step explanation:

a full circle is equal to 360

for #3, i used the equation (2x-10) + (x+4) + (x+10) = 360

combine all like terms and get 4x + 4 = 360

subtract 4 from both sides

4x + 4 = 360

4x = 356

divide 4 from both sides

x = 89. from here put 89 where x is . angle BGD and angle CGA are the same so 89 + 4 = 93

for #4, use the equation 45 + 3x - 19 = 110

combine like terms and get 26 + 3x = 110

subtract 26 from both sides and then divide by 3

3x = 84

x = 28

place 28 where x is and find the matching angle which is 70.

HOPE THIS HELPS!!

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
