Find the value of x.

Mathematics
1 answer:
Anna [14]3 years ago
6 0

Answer:

x = 5.

Step-by-step explanation:

ZY = 2*2x = 4x.   (Parallel line in a triangle theorem).

XZ = 2 * (4x + 1) = 8x + 2

XY = 2 *(2x + 3) = 4x + 6

So the perimeter 88 = 4x + 8x + 2 + 4x + 6

88 - 8 = 16x

16x = 80

x = 5.

(Sorry but I can't remember the exact name of the theorem).

The missing values are 28° and 62°

<h3>What are perpendicular lines?</h3>

Perpendicular lines are said to be two lines that intersect or meet each other at right angles, that is 90 degrees.

From the information given, we have that;

Line AC ⊥ Line BE

Where:

  • m ∠ ADE = (x + 5)°
  • m ∠ DBE = (3x - 7)°

Hence,

x + 5 + 3x - 7 = 90

collect like terms

4x = 90 + 2

4x = 92

Make 'x' the subject

x = 92/ 4

x = 23

For the missing values

m ∠ ADE = (x + 5)° = ( 23 + 5) = 28°

m ∠ DBE = (3x - 7)° = (3(23) - 7) = 62°

Thus, the missing values are 28° and 62°

sveta [45]

Answer:

log(32/125)

=log32 - log125 [log(x/y)=log(x) - log(y)]

=log(2)^2 - log(5)^3

=2log2-3log5 [log(x)^p=p log x]

=2a-3b
