Answer:

1. 7.6 = c

2. 45 = c

Step-by-step explanation:

1. 3^2 + 7^2 = c^2

9 + 49 = c^2

58 = c^2

square root both sides = 7.6 = c

2. 27^2 + 36^2 = c^2

729 + 1296 = c^2

2025 = c^2

square root both sides

c = 45

In triangle abc, the perimeter is 36, and ab=ac. line ad is perpendicular to bc at the point d, and triangle abd's perimeter is
Musya8 [376]
Let x=ab=ac, and y=bc, and z=ad.

Since the perimeter of the triangle abc is 36, you have:

Perimeter of abc = 36
ab + ac + bc = 36
x + x + y = 36
(eq. 1) 2x + y = 36

The triangle is isosceles (it has two sides with equal length: ab and ac). The line perpendicular to the third side (bc) from the opposite vertex (a), divides that third side into two equal halves: the point d is the middle point of bc. This is a property of isosceles triangles, which is easily shown by similarity.

Hence, we have that bd = dc = bc/2 = y/2 (remember we called bc = y).

The perimeter of the triangle abd is 30:

Permiter of abd = 30
ab + bd + ad = 30
x + y/2 + z =30
(eq. 2) 2x + y + 2z = 60

So, we have two equations on x, y and z:

(eq.1) 2x + y = 36
(eq.2) 2x + y + 2z = 60

Substitute 2x + y by 36 from (eq.1) in (eq.2):

(eq.2') 36 + 2z = 60

And solve for z:

36 + 2z = 60 => 2z = 60 - 36 => 2z = 24 => z = 12

The measure of ad is 12.

If you prefer a less algebraic reasoning:

- The perimeter of abd is half the perimeter of abc plus the length of ad (since you have "cut" the triangle abc in two halves to obtain the triangle abd).

- Then, ad is the difference between the perimeter of abd and half the perimeter of abc:

ad = 30 - (36/2) = 30 - 18 = 12

Please solve this problem ​
asambeis [7]

Answer:

(4) 0

Step-by-step explanation:

<u>Given:</u>

  • cos²27°×cos²34°×...×cos²167 = ?

<u>Looking at the angles measures, they form series of: </u>

  • 27, 34, 41, ..., 167

This is AP with the first term of 27 and common difference of 7

<u>We can see one of the terms of this AP is 90</u>

  • 27+9*7 = 27 + 63 = 90

Since cos 90° = 0 ⇒ cos²90° = 0 and therefore given series equals to zero as one of the terms of multiplication is zero.

<u>So correct answer choice is</u>  Option 4) 0
