What are the values of x and y given that ABCD ≅ EFGH?
Margarita [4]

Answer:

x = 7

y = 8

Step-by-step explanation:

Since the shapes are similar then <B = <F and <A = <E

<B = <F so

10x + 65 = 135 subtract 65 from both sides

10x = 70 divide both sides by 10

x = 7

<A = <E so

4y - 4 = 28 add 4 to both sides

4y = 32 divide both sides by 4

y = 8

ASAP MAJOR HELP NEEDED. I really need help. I am very confused on how to do this please help.
alexandr402 [8]

Because the 2 sides of the triangle are the same, they are both 21, the two bottom angles would also be the same.


The 3 inside angles of a triangle must equal 180 degrees.


The top angle is given as 38, so the remaining two angles must equal 180 - 38 = 142 degrees.


Since the 2 bottom angles would be the same, divide 142 by 2 to get x.

X = 142 / 2 = 71 degrees.

Trigonometric Identity help​
vovikov84 [41]

Answer:

sin\pi/4 * sin\pi/6 = 1/2 *(cos \pi/12 - cos 5\pi/12)

Step-by-step explanation:

Formula:- sinX sinY = (1/2) [ cos (X - Y) - cos (X + Y) ]

sin(π/4)sin(π/6)

= (1/2)[cos(π/4 - π/6) - cos(π/4 + π/6)]

= (1/2)[cos(3π/12 - 2π/12) - cos(3π/12 + 2π/12)]

= (1/2)[cos(π/12) - cos(5π/12)]
