Angles in a triangle equal 180 so if you do 48+ 85 this would equal 133 and take 133 away from 180 you get 47
Your answer is 47 degrees

Answer:

x= 47

Step-by-step explanation:

sum of angles in a triangle are 180

so 180 = x + 85 + 48

=> 180 - 85 - 48 = x

=> x= 47

or x= 180- (85+48)

=> x= 180 - 133

x = 47

64=[(96 divided by 8) times 5]-42
bogdanovich [222]

Answer:

that statement is not true

Step-by-step explanation:

64=[(96÷8)5}-42

64={(12)5} - 42

64= (60)-42

64=18

but that with subtraction. if you multiply 60 by negative 42 you get -2520 which is still not true
