Make the whole number as an improper fraction. example, 2 7/12 would be 31/12 and then you can multiply 8/1 x 31/12
Answer:
0.1221
Step-by-step explanation:
Answer:
There are 6 equilateral triangles
you get an isosceles triangle
the height of the equilateral triangle is 4
this is all I have so far :)
Let's convert the equation in point-slope form to slope-intercept form.
y - 4 = -(x - 6)
Multiply everything out.
y - 4 = -x + 6
Add 4 to both sides.
y = -x + 10
To be perpendicular, the slope of the new has to be the reciprocal of the other line. To slope in this equation is -1/1. To get the reciprocal, flip the numerator and denominator and change the sign too.
-1/1 becomes 1/-1, and changes to 1/+1, or 1.
y = x + b
Input the coordinate point and solve for b.
-2 = -2 + b
Add 2 to both sides.
0 = b
y = x
Answer:
x = 17
, y = 34
Step-by-step explanation:
Since the triangle is right use trig ratios to find x and y
note exact values sin30° = 
, tan30° = 
sin30° = 
= 
multiply both sides by y
y sin30° = 17 ( divide both sides by sin30° )
y = 
= 34
tan30° = 
= 
multiply both sides by x
x tan30° = 17 ( divide both sides by tan30° )
x = 
= 17
