Not sure if 13x-10 or 3x-10 since that is an 'l' so therefor I will solve for both they add to 90 so add the 2 angles if 13x-10 go to AAAAAAAA if 3x-10 then go to BBBBBBBB
AAAAAAAAAAAAAAAAAAAAAAA 2x-10+13x-10=90 group like terms 2x+13x-10-10=90 addd liket erms 15x-20=90 add 20 to both sides 15x=110 divide both sides by 15 x=22/3 subsitute 2x-10 2(22/3)-10 44/3-10 14 and 2/3-10 4 and 2/3 is one angle then subtract the other one 90-4 and 2/3=85 and1/3 the angles are 4 and 2/3 and 85 and 1/3
BBBBBBBBBBBBBBBB 2x-10 and 3x-10 add 2x-10+3x-10=90 gropu liek terms 2x+3x-10-10=90 add likke terms 5x-20=90 add 20 5x=110 divide y 5 x=22 subsitute 2(22)-10 44-10 34 subtract 90-34=56 the angles are 34 and 56 degrees
I would go with 34 and 56 because you sometimes deal with whole numbers more in math
The formula for the volume of a cone is V=1/3(pie)r²h. So if you know the radius and the voume, plug those numbers in for V and r respectively and solve for h
