To find x, we simply need to subtract the sum of the other two sides from 73.
35+11=46
73-46=27
So x = 27mm
58% is about equal to 60%, 10% of 121 is 12.1.
12.1 * 6 = 72.6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18
Answer:
see explanation
Step-by-step explanation:
Given
tan a = 
= 
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h = 
= 41 , thus
sin a = 
= 
cos a = 
= 
Hey there!!
We know:- <em>Vertically opposite angles are equal. </em>
Hence,
Angle 1 = Angle 2
... 6x + 11 = 10x - 9
... 20 + 6x = 10x
... 20 = 4x
... x = 20 / 4
... x = 5
Angle 1 = 6x + 11
... 6 ( 5 ) + 11
... 30 + 11
... 41
<em>Hence, the measure of angle 1 is 41 degrees. </em>
Hope my answer helps!
