Answer:
x ≈ 0.814
Step-by-step explanation:
use
sin(24)= x/9
sin^-1 (x/9) = 24 degrees
So instead of 3/4 we’re gonna make it easy for us and multiply the top and bottom
1+1/8+1+6/8
2+7/8
Answer: 2 7/8
The perimeter of a square is the sum of all its sides' lengths
That means: perimeter =4*(7m+1)/3
Answer:
By comparison of the sides.
Step-by-step explanation:
If triangles are similar, that means their angles are equal and sides are proportional.
If you already have a proportion of two corresponding sides between triangles, then use that proportion and set it equal to a side you already know the measurement to. Hopefully that side is corresponding to your missing measurement, and you can then solve it.
-7(4-2)+1=15-7x
-7 x 2 + 1 = 15 - 7x
-14 + 1 = 15 -7x
-13 -15= -7x
-28 = -7x
-28 / -7 = x
x=4
3x - 54 = 160 >I just flipped the equation
3x - 54 (+54) = 160 (+54) added 54 each
3x = 160
3x/3 = 160/3 >divided 3 to each side
x = 160/30
or 53.33333333333333333~
