Answer:

hi there!

the correct answer is: 29 degrees

Step-by-step explanation:

if you refer to the picture I have drawn below angle b is supplementary to the the 119 angle (i know I accidentally wrote 118) that means in order to find angle b you need to do 180-119 which equals 61

then since all angles in a triangle add up to 180, you need to perform (180-90-61) which equals 29

Step-by-step explanation:

m<DAC is the exterior angle of the right angle triangle, where m<ACB and m<ABC are the interior angles of the triangle opposite to the exterior angle

Sum of the opposite interior angles is equal to the exterior angle

m<ACB+ m<ABC=m<DAC

a°+90°= 119°

a°=119-90°

a°=29°

True or false 7 have a greater absolute value than -9. Explain.

Taya2010 [7]

False because when considering the magnitude of the numbers, 7 is only 7 away from zero which -9 is 9 away from zero. 9>7 so therefore, this statement is false.
