Answer:
1/ √2
Step-by-step explanation:
Here, we want to get the value of sin 45
Mathematically the sine is the ratio of the opposite to the hypotenuse
The opposite here is 1 while the hypotenuse is
√2
so the value of sin 45 will be;
1/ √2
Answer:
Perimeter= 44.2 inches
Area= 70 inches squared
Step-by-step explanation:
Perimeter- Add all your sides together (10+ 17.2+2+3+7+5=44.2)
Area- 1/2bh (b=base, h=height)
Your base is the bottom of the triangle, so 2+7+5=14.
14 is your base
Your height is the 10
1/2 *14*10
1/2 of 14 is 7
7*10= 70
Don't forget to write inches squared or it will be wrong
Hope this helps :)
Answer:
50 degrees.
Step-by-step explanation:
Angle FGE =
because angles on a straight line add up to 180 degrees.
Angle EFG =
(Angles in a triangle add up to 180)



Add 20 to both sides:


Subtract 6x from both sides:


Angle 
2.54 * 12=30.48, so 30.48 in one foot, then multiply that by three for a yard, so for a yard it is 91.44 .
