Answer:

x = 35

y = 7

Step-by-step explanation:

See how the image looks like two overlapping triangles. It is given that the triangles are congruent. Its easier to see whats what if you draw the triangles separately. I also flipped over the triangle on the right so they match. Record the given angle measures. Since A is 45° then D is also 45°. DBC is 30°, so we can find the missing angle in triangle DBC. Angles in a triangle add up to 180° so

C + 45 + 30 = 180

C + 75 = 180

C = 105°

This is angle DCB.

Now all the angles are marked. We can set up equations to find x and y. see image.

the front of a tent is an equilateral triangle with the ratio of its base b toits height h given by b/h+2/3 rewrite the equation
kap26 [50]

Answer:

h = b(√3)/2

Step-by-step explanation:

The ratio of base to height of an equilateral triangle is ...

... b/h = 2/√3

Multiplying both sides of the equation by (√3)h/2, we get

.. h = b(√3)/2 . . . . . . your equation with h as the subject

The perimeter of the triangle below is 6a+2b-5 units. write an expression to represent the length in units, of the missing side
ANTONII [103]

Answer:

3a + 5b - 2

Step-by-step explanation:

The perimeter is the sum of all 3 sides of the triangle.

To find the missing side (x ) sum the 2 known sides and subtract from the perimeter.

x = 6a + 2b - 5 - (2a + 6b - 6 + a - 9b + 3 ) ← simplify parenthesis

  = 6a + 2b - 5 - (3a - 3b - 3 ) ← distribute by - 1

  = 6a + 2b - 5 - 3a + 3b + 3 ← collect like terms

  = 3a + 5b - 2 ← length of missing side
