4/10^2 = 0.04
which is equal to:
4x10^-2
As there are two digits behind the decimal point up to( and including the 4) thus the 10^-2
And as the digit is a 4 you multiply 10^-2 by 4
Answer:
x = 30
Step-by-step explanation:
because the interior angles of a triangle = 180° so if you subtract 90° you get 90. in order to get 90 you can use the equation x + 2x = 90 which you will then get x = 30

Answer:
11. a)50 12. a)40
Step-by-step explanation:
sum of all three angles of trinagle=180
so
111.
80+50+x=180
130+x=180
x=180-130
x=50
12.
60+90+x=180
150+x=180
x=190-150
x=40
Answer:
Distance = 5
Step-by-step explanation:
x2 = 3
y2 = 1
x1 = 7
y1 = -2
=> d = Square root of (3 - 7)^2 + (1 + 2)^2
=> d = Square root of (-4)^2 + (3)^2
=> d = Square root of 16 + 9
= d = Square root of 25
d = 5
