An isosceles triangle has an angle that measures 30°. Which other angles could be in that isosceles triangle? Choose all that apply.

the other angles would have to be 75 degrees each

Step-by-step explanation:

All of the angles in a triangle make up 180 degrees. an isosceles triangle has 2 angles that are the same and 1 that is different. Since you were given that 30 degrees, you would subtract that from 180, which would give you 150. Since the angles would have to be equal to each other, you would divide 150 by 2 and you would get 75.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
