Since they are congruent, all will be the same value.
c = 3
∠d = 38° (asked for the angle)
g = 5
9 is a parallelogram because parallelograms have parallel sides. and for 10 set 7x+3=3x+35 because its a rectangle and the side lengths are equal. solve to get
4x=32
x=8
x=x, so plug in 8for x for bc=2x+5
16+5=21
then plug in x to both equations just in case (ab and dc)
i got 59 and 59)
so 59 and 21 are the side lengths, so now use that calculator for the Pythagorean theorem.62.63 about.cuz its a right triangle.
Answer:
39 degrees
Step-by-step explanation:
Right triangle
40 ft tree = opposite side
50 feet = adjacent side
tan (angle) = opp / adj = 40 /50
arctan (40/50) = 38.66 degrees ~ 39 degrees
1/3 ÷ 2 =
1/3 x 2/1. you do this by doing the reciprocal of 2, and then you do KCF ( keep, change, flip,)
keep 1/3 change ÷ to × and flip 2/1 to 1/2.
1/3 x 1/2 = 1/6.
hopefully this helps you
Answer:
307cm²
Step-by-step explanation:
This is a composite firgue so we need to split the two shapes, then find the area of both.
find the area of the rectangle
A=b*h
A=18*10
A=180
then find the area of the semicircle
A=1/2Pi*r²
A=1/2Pi*81
A=127.75 (We need to find the radius of the semicircle then square it)
then add the two areas 180+127.75=307.75
find the closet unit its
307cm²
