Answer:
55.7 in.
Step-by-step explanation:
I assume the figure is a rectangle and a half circle.
The three sides of the rectangle that need to be added toward the perimeter measure 15 in., 10 in., and 15 in.
Then you need the circumference of the half circle which has a 10-inch diameter.
circumference = (pi)d
circumference = 3.14 * 10 in. = 31.4 in.
We only need half the circumference, so we have 31.4 in./2 = 15.7 in.
Now we add the three sides of the rectangle listed above and the circumference of the half circle.
perimeter = 15 in. + 10 in. + 15 in. + 15.7 in.
perimeter = 55.7 in.

Answer:
5
Step-by-step explanation:
4 times 5/2 times 1/2 is 5

For the first one you would do:
X rad 3=7 divide by rad 3 in both sides and you don’t wanna leave a radical in the denominator so multiply rad 3 in both denom. And numerator and then you get 7rad3/3.
A 30:60:90 triangle always have n:2n:n rad 3 so since 2n=10 you would get n=5 and since BC is n rad3 so you would get 5rad 3.
In a 45:45:90 triangle it is n:n:n rad 2, since AC=3 then AB= 3 and then BC= 3 rad 2
Since AC and AB are congruent you they both would be 12 so it is true.
