Answer:
x=58 degrees
Step-by-step explanation:
A line is 180 degrees. So x+90+32=180. 32+90=122. Now you do 180-122 and you will get 58.
Answer:
Step-by-step explanation:
Given a number n then the multiplicative inverse is 
The product of a number and it's multiplicative inverse = 1
Given 2, then multiplicative inverse is
Answer:
The percentage of people is 60%
Step-by-step explanation:
The reasoning this is the answer is because you to find the percentage you take the amount which does the thing or the part of the whole which is included in the slection ad you divide it by the total and multiply that by 100 so (2100/3500)*100 and that gives you 60%

Sine of the angle = opposite side over the hypotenuse
sin(42°) = 6.5/h
rearrange, solve for h
h = 6.5/sin(42°)
h = 9.7 cm
For the other triangle, the angle is unknown. I'd split it into two right triangles; down angle x since it is an isosceles it will be bisected into two equivalent triangles.
The hypotenuse we just found is now split in half. 9.7/2 = 4.9 base of the new smaller right triangle.
The new hypotenuse of the smaller triangle is 7.4 cm
Then you have..
sin(x/2) = 4.9/7.4
sin(x/2) = 0.67
use inverse sine function
arcSin(0.67) = x/2
41 = x/2
82° = x
There are many ways to solve this problem. This is just what I thought of first using trig.
