Similar means angles are the same

Congruent means angles and sides are the same.

Sail 1 and sail 2 have the same angles but the sides are not the same.

So sail 1 and sail 2 are similar.

The hypotenuse of a right triangle is 6 inches. if one of the legs is 2 inches, find the degree measure of each angle

miskamm [114]

A and b are the 2 smaller sides, and c = hypotenus; only for right triangles,
Pythagorean Theorem states that:
${c}^{2} = {a}^{2} + {b}^{2}$
given c = 6 in., a = 2 in.
${c}^{2} = {a}^{2} + {b}^{2} \\ {6}^{2} = {2}^{2} + {b}^{2} \\ {b}^{2} = {6}^{2} - {2}^{2} = 36 - 4 \\ \sqrt{ {b}^{2} } = \sqrt{36 - 4} = \sqrt{32}$
$b = \sqrt{32} = \sqrt{16} \times \sqrt{2} = 4 \sqrt{2} \\ b = 5.66 \: inches$
So the three side are 2, 6, and 5.66 inches

3x+3y=6 and 5x-6y=15

Anna71 [15]

Multiply first equaton by 2 and add to the other equation

6x+6y=12
5x-6y=15 +
11x+0y=27

11x=27
divide both sides by 11
x=27/11

sub back
3x+3y=6
divide both sides by 3
x+y=2
(27/11)+y=2
2 and 5/11+y=2
minus 2 and 5/11 both sides
y=-5/11

x=27/11
y=-5/11
(27/11,-5/11)

What are the measurements of the little 2 small cube things on each side, better yet what's the surface area? Thank you

Arisa [49]

Answer:

166 units²

Step-by-step explanation:

We know that:

W = 7
L = 5
H = 4

Surface area is the area of the faces of the cuboid.

Work:

=> 2(7 x 4) + 2(5 x 4) + 2(5 x 7)
=> 2(28) + 2(20) + 2(35)
=> 56 + 40 + 70
=> 166 units²

Hence, Option C is correct.

Hoped this helped.
