Answer:
To find one tenth of a number, simply divide it by 10 . The easiest way to do that is to : cross off a zero at the end if there is one. move the decimal one place to the left.
Step-by-step explanation:
90-2x + 3x + 60 = 180
90 + x + 60 = 180
x + 150 = 180
x = 30°
Answer:
48
Step-by-step explanation:
7-1=6 6 times height which is 8 is 48.
Answer:
a = 5√7
Step-by-step explanation:
Sides of a right triangle follow the Pythagoras theorem,
By Pythagoras theorem,
(AB)² = (BC)² + (AC)²
c² = a² + b²
If b = 9 and c = 16,
(16)² = a² + 9²
256 = a² + 81
a² = 256 - 81
a = √175
a = 5√7
Therefore, measure of third side a = 5√7
