If one Angle is = 30
And the other two angles are equal
Given: x = l
ATQ
⇒30+x+l= 180
⇒x + x = 180-30
⇒2x = 150
⇒x = 150/2
⇒x = 75
Therefore x = 75
And the angles are 30, 75 and 75

4) 21
5) 36
6) 29.25
I used porpotions on all of these.
Sorry I don't remember the units.
Step-by-step explanation: These two decimals are equal to each other because the zeroes in 7.400 don't change it's value.
So, after a decimal point, zeroes don't change the value of the decimal.
So we can simply drop the zeroes to see that 7.4 = 7.4.
The answer is c
