what is the missing angle measurements for the isosceles triangle it has a picture of a triangle and has 70°
bulgar [2K]
Well if they part that has 70 degrees is congruent to any other side it is 70 + 70 which equals 140 and 360 which is a complete circle minus 140 is 220  the missing angels are there fore 70 and 220   or if the angle isnt congruent then the other sides must be so what plus itself on top of adding 70 will get us 360. lets find out what 220 in half is   since 220 and 70 equals 360. 110 is 220 in half so the sides missing on this could be 110 110

What is a way to write 11 more than twice x is less than 44
madam [21]

(2x) + 11 < 44

x is multiplied by two because we are looking for twice of x. 11 is added to the 2x because we are looking for eleven more than the sum of twice of x. Since 2x + 11 is less than 44, we use the lesser than ( < ) symbol.
